ACID properties act as a framework, ensuring that each transaction completes fully or has no effect (atomicity), adheres to predefined rules (consistency), operates independently (isolation), and remains permanent once committed (durability). Together, these properties ensure the safe and accurate handling of data.

What is ACID?

1. Atomicity

This property ensures that every transaction is treated as a single, indivisible unit. If any part of the transaction fails, the entire operation is rolled back, leaving the database unchanged.

For example, if an e-commerce transaction involving inventory update and payment fails at the payment step, atomicity ensures that inventory adjustments are not applied either.

2. Consistency

This property guarantees that a transaction brings the database from one valid state to another, preserving the defined rules and constraints. Any transaction violating these rules will be rejected.

For instance, a banking system disallows unauthorized overdrafts by enforcing consistency rules.

3. Isolation

The isolation property ensures that transactions are executed as if they were occurring one at a time, even when multiple transactions are processed concurrently. This prevents interference between transactions.

For example, two people buying the last item in an inventory at the same time would not both succeed; isolation would ensure only one transaction completes first.

4. Durability:

Once a transaction is committed, its effects are permanent, even if the system crashes immediately afterward. A durable system ensures that completed transactions are stored persistently.

One example would be placing an order in an e-commerce app, the details remain secure, and the order can be retrieved even if the system fails immediately after the transaction is completed.

Why are ACID transactions important?

ACID properties are most commonly used for transactional databases that handle real-time updates and maintain critical information. Without ACID compliance, the reliability of these systems lessens, which can cause issues down the road.

For organizations that maintain databases supporting healthcare systems, patient data and medical records must be highly accurate and consistent to comply with industry regulations, such as HIPAA. Even a small inconsistency could lead to a misdiagnosis or a data breach.

Conclusion

ACID properties collectively enable databases to handle complex transactions reliably, even under challenging conditions like system crashes or concurrent operations. This makes them ideal for organizations that handle large databases. For IT experts, understanding ACID properties makes it easier to safeguard critical business data.

Types of exploits

Exploits come in a variety of forms that IT security professionals should be aware of.

• Remote exploits

Remote exploits allow attackers to manipulate a system from afar.

• Local exploits

Local exploits require physical access to the targeted endpoint device. Cybercriminals escalate user privileges or abuse systems internally, such as privilege escalation attacks.

• Zero-day exploits

Zero-day exploits usually have lesser-known vulnerabilities unknown to the vendor or the public. Without available patches, attackers weaponize such loopholes to gain an advantage before they’re addressed.

• Browser exploits

Browsers exploit target vulnerabilities within web browsers or plugins, such as Flash and Java, which are targeted to install malware or steal information.

• Denial-of-Service (DoS) exploits

By abusing system vulnerabilities, DoS attack exploits make resources or services unreachable to legitimate users, causing disruptions.

What is an exploit kit?

An exploit kit is a pre-packaged set of tools used by hackers to streamline exploit-based cyberattacks. These kits often target specific vulnerabilities and automate the exploitation process, making cyberattacks more accessible to less-skilled attackers. Exploit kits are typically distributed through malicious websites or ads, tricking users into unintentionally initiating the attack process.

How to tell if there’s an exploit attack

Recognizing the symptoms of an exploit attack allows IT teams to resolve issues and safeguard data from unauthorized parties quickly.

Unusual network traffic

Sudden spikes or irregular patterns in network traffic mean that exploit attempts.

Unstable performance

Applications affected by an exploit attack often behave unpredictably, leading to error messages, restarts, or system crashes.

Suspicious files and modifications

Files that have been moved to unexpected locations or system files that enact sweeping modifications to system configurations could sometimes indicate an exploit attack.

How to protect devices from exploits

• Consistent patch distribution

Software left unpatched is one of the most common exploit vectors. Organizations should invest in patch management software to ensure that their software always has the latest security patches installed. With NinjaOne’s patch management software, users can automate all the necessary tasks, from scanning items,

• Vulnerability scanning

Regular scans help identify missing patches or patches that failed to install, allowing users to address the patching schedule before the exploit attack.

• Security awareness training

Educating IT teams and organizations on common vectors for attack, such as phishing, and safe browsing practices helps reduce error-based exploits.

Deploying endpoint security to prevent exploits

Exploit attacks target weaknesses in software, systems, or processes, and the impact can range from data theft to complete operational shutdowns. IT experts can stay ahead with vulnerability management like NinjaOne.

In this article, we explore the difference between agile vs waterfall, and describe each one’s methodologies, advantages, disadvantages, and applications.

What is agile project management?

Agile project management approaches each project—or, in the context of IT, each piece of software—as a series of smaller bits, allowing for changes after each minor milestone. Through agile methodology, projects are broken down into “sprints” that are repeatable throughout the project’s life.

Agile project management is much more flexible than other approaches. It allows the project team to gather information about the current sprint and determine what went well and what didn’t, so they know where changes must be made moving forward. This results in a circular path of development rather than a linear one, creating a continuous feedback loop.

It is recommended for projects requiring customer input or not having a clear end goal in mind.

What is the waterfall method?

In contrast, the waterfall method uses a linear approach to project management. Using waterfall, projects are completed in steps, and each step must be completed before moving forward. As such, all projects that use the waterfall method have a clear result, follow clear steps, and have various success metrics.

The waterfall method generally follows five steps:

• Analysis: The first step involves identifying the project’s key requirements, including its end goal and timelines.
• Designing: This is where the project managers design potential solutions to reach the planned objective.
• Implementation: This is where the designed project is implemented.
• Testing: Project managers test the solution after implementation to determine if all the metrics and timelines (as discussed during step 1) are being met.
• Maintenance: This updates the solution to match customer or stakeholder feedback.

As seen, moving on to the next step is impossible without first considering the previous one. This makes the waterfall method idea for more straightforward projects that do not require high flexibility.

Agile vs waterfall: Which one is better?

The best way to see the differences between the two methodologies is through this table:

Though there is a clear distinction between the two, neither is “better” than the other. Both agile and waterfall methodologies offer different advantages, making them suitable for various projects. The agile method is ideal for organizations prioritizing flexibility and ongoing collaboration, whereas the waterfall is better suited for projects with clearly defined requirements and fixed timelines.

Neither approach is inherently better for software development; the choice depends on your organization’s needs, the nature of the project, and your team dynamics. By evaluating factors such as project scope, customer involvement, and tolerance for change, your organization can determine which methodology best aligns with your needs and goals.

Choosing the right approach for your needs

There are no hard and fast rules when deciding between agile and waterfall in software development. Ultimately, the “best” methodology depends on your organization’s unique needs and operational structure.

Similarly, in endpoint management, selecting the right tool is crucial for optimizing workflows and achieving organizational objectives—we’ve written a more comprehensive guide on finding the best endpoint management tool here.

NinjaOne endpoint management is a prime example of a solution that supports diverse IT environments and is suitable for businesses of all sizes and industries.

What is quarantine?

Quarantine is the process of moving a file suspected to be infected by any type of malicious software. This isolation process prevents the potentially compromised file from infecting other parts of a system. This gives IT security teams ample time to analyze and neutralize the threat, preventing it from exacerbating the situation.

How does quarantine work?

IT security teams go through several steps when quarantine is performed. Here’s a breakdown of how the process is done:

• Detection

IT security teams typically rely first on tools vital for detecting possible system threats. These tools include antivirus, anti-malware, and firewall programs that continuously scan a system for potential anomalies, suspicious activities, or malicious files. Security teams also look over network security by depending on solutions such as network intrusion detection systems (IDS) and intrusion prevention systems (IPS) that can monitor network traffic for signs of attack.

• Identification

After detection, IT security teams identify the threat, which involves threat analysis. Once a potential threat is detected, the security team looks into the software they utilize, helping them analyze its nature and severity. The threat is then classified based on its type, whether a virus, worm, or ransomware.

• Isolation

Isolation encompasses different stages, but it typically begins with file isolation. File isolation, or file quarantine, is moving suspicious files to a secure and separate location to prevent them from infecting other files, executing harmful commands, or spreading.

The next step is network quarantine, where infected devices are temporarily disconnected from the network, limiting the spread of infection. In some cases, user quarantine is also necessary, where specific user accounts are restricted to prevent further damage to the whole system.

• Analysis and response

Following isolation, the quarantined threat may undergo deep inspection by security experts in a controlled environment. This step is crucial to understanding the threat’s behavior and identifying system vulnerabilities. Additionally, security teams may attempt to remove the threat or disinfect the infected files using security software. Vulnerable software is also updated with security patches to prevent future attacks.

• Monitoring and prevention

Preventive measures are implemented by deploying security systems that continuously scan the system and network for potential threats. Security systems are consistently being updated with the latest security patches to combat possible future threats. Monitoring and prevention are also amplified by educating system users to recognize and avoid phishing attacks, malicious downloadable files, and other security threats.

Best practices for quarantine

Effective quarantine policies and procedures

• Guidelines for analysis, removal, and restoration should be communicated and agreed upon to establish clear policies and procedures for handling quarantined items.
• Since threats continuously evolve, there should be consistent reviews and updates of quarantine policies.
• Training and education are also a key part of threat prevention. Educating staff on proper quarantine procedures, identifying and responding to threats, and making informed decisions are some of the most crucial cybersecurity best practices organizations can implement.

Regular monitoring and review of quarantined items

• Threat analysis is a continuous process. This is done by regularly checking the quarantine folder for new items to see if they are suspects for potential threats.
• There may also be instances when quarantined items are falsely flagged. Ensuring that these items fall under the allowlist by periodically reviewing your quarantine folder.
• Take prompt action to remove or restore quarantined items or to further investigate potential threats.

Incident response plans for quarantine breaches

• One effective way to prevent threats is to employ a dedicated response team that is assigned to handle security breaches.
• Another best practice is developing procedures for containing quarantine breaches, like isolating infected systems and blocking network traffic.
• An efficient recovery plan to restore affected systems and data should also be created and enforced.
• Continuous knowledge sharing and research can help improve future response efforts by conducting a post-incident review.

Conclusion

Quarantine is a significant step in damage control, preventing further system compromise. It allows for isolating potentially harmful elements that may otherwise affect other systems or data. While quarantine is an important component that obstructs system damage, it should be followed up with best practices to enhance security. By combining quarantine with a robust security posture, organizations can significantly reduce the risk of cyberattacks and protect their valuable assets.

As you can imagine, your master data needs to be accurate, consistent, and reliable so you can make more strategic decisions. It is crucial to any data governance plan and has its own management approach called master data management.

Different types of data

It’s worth noting that there is no universal definition of master data for all organizations. What your company considers master data will depend on your business model and operational needs. However, all critical data to your company’s operations should be considered master data.

To better understand this delineation, let’s discuss the six primary types of data:

• Unstructured data: This type of data does not follow any specific format and includes assets such as emails, white papers, and product specifications.
• Transactional data: This is data generated by business events and operations, including sales, invoices, claims, and purchase orders.
• Metadata: This is data that provides information about other data, such as report definitions and log files. In SEO, for example, metadata describes the information on a specific webpage.
• Hierarchical data: This is data that establishes relationships between other data, such as customer segmentation.
• Reference data: This is data used to categorize other data, like country and currency codes.
• Master data: Foundational and referential data that defines key business entities. The other five types of data can be used to provide deeper insights into master data objects.

Master data can be further categorized into:

1. Customer data
2. Product data
3. Supplier data
4. Location data
5. Other data related to contracts, warranties, and licenses

Regardless, all master data must follow a governance plan to ensure data sets are transcribed in the same format and structure. This minimizes the risk of dirty data and helps maintain data consistency throughout.

Why is master data important?

As mentioned, master data is often referred to as the “single source of truth”—and for good reason. Consider how your organization manages complex data sets across various departments. It’s likely that some level of dirty data (such as data duplication) exists, requiring your IT team to identify and validate the most accurate data set to provide to stakeholders.

For instance, if you’re a managed service provider (MSP) evaluating an endpoint management company, having the correct and most reliable data is critical for informed decision-making. But what happens when different departments interact with the same customer and record inconsistent information? How do you reconcile these discrepancies? How can you consolidate data to determine which version is accurate and reliable?

Establishing master data as the single source of truth requires rigorous processes to standardize, cleanse, and validate data across your organization. This ensures all departments operate with a unified and accurate view, supporting better collaboration, decision-making, and customer engagement.

10 Key components of master data

In general, the key components of master data include:

• Identifier (ID): This is a unique code or value used to identify each instance of a data entry.
• Name and description: This provides a human-readable label or summary for the data entity.
• Attributes: These are the properties or characteristics of a data set, providing additional context.
• Classification: This categorizes a data point into a predefined group.
• Relationship: This map shows how data points may be related to one another, helping reveal their context within the broader data ecosystem.
• Data lifecycle: This tracks the state and history of the data point over time, including creation dates, modification history, and status indicators.
• Hierarchies: This defines the structure and organization of data entities within a specific domain.
• Business and validation rules: These rules establish criteria for the data entry and ensure compliance. For example, validation rules can require all dates to be formatted as MM/DD/YYYY instead of DD/MM/YYYY.
• Geospatial data: This includes information about the physical location of the data entity if needed.
• Ownership and data stewardship: Ownership identifies the users or teams accountable for managing the data entity.

10 Benefits of master data

• Improved decision-making: Master data provides a unified and accurate view of business-critical entities, helping leaders make more informed decisions.
• Enhanced operational efficiency: Clean, consolidated data contributes to operational efficiency. Businesses can streamline workflows, reduce redundancies, and improve overall productivity.
• Better customer experience: Accurate master data lets organizations gain a 360-degree view of their customers. This unified perspective helps tailor interactions, predict customer needs, and offer personalized experiences.
• Reduced costs: Master data, through master data management, minimizes errors and inefficiencies. This can lead to cost savings.
• Maintain compliance: Master data ensures that organizations maintain accurate records, meet compliance standards such as GDPR and HIPAA, and avoid costly penalties for noncompliance.
• Improve collaboration across departments: A single source of truth ensures all departments operate with consistent data.
• Increases data quality: Clean data minimizes risk and errors, supporting the overall integrity of business operations.
• Enhances reporting and analytics: Accurate master data contributes to more robust reporting and analytics. Organizations can generate meaningful insights, identify trends, and confidently track performance metrics.
• Helps make organizations more agile: As businesses grow or evolve, master data can provide the foundation to scale processes seamlessly.
• Strengthens vendor and supplier relationships: Master data enables accurate tracking of supplier data, contracts, and performance. This fosters transparency and can build stronger partnerships between vendors and suppliers.

What is file encryption used for?

File encryption safeguards business-critical files, personal data, or customer information against unauthorized access or data breaches. Here are a few common uses for file encryption:

• Secure data transfer

Encryption protects files shared or transferred via email, shared in the cloud, or exchanged between devices.

• Data protection

Encrypted backups ensure that even if a device is stolen or compromised by a cyberattack, hackers will be unable to access the files. By encrypting backups, the IT team can prevent the event of some common cyberattacks, such as ransomware incidents, ensuring that essential files can be restored.

• Compliance

For organizations with strict privacy regulations, such as GDPR or HIPAA, file encryption adds an extra layer of protection for sensitive customer or patient information, making compliance management easier for IT teams. Even if devices or servers are compromised, encryption ensures attackers cannot decipher the files without the required credentials or keys.

What files can be encrypted?

Nearly any type of file can be encrypted. This includes files that contain names, addresses, financial records, health records, and even multimedia files. System files critical to business operations, such as configuration files or password databases, benefit from encryption to prevent cybercriminals from accessing them.

When to use file encryption

Encryption isn’t required for every file, but end-users and IT administrators should consider utilizing it to ensure data integrity and security.

For example, businesses with remote or hybrid work arrangements should use file encryption to ensure their data remains protected. Remote employees often need to access and share files through cloud storage. While many cloud providers offer encryption, encrypting files before uploading them adds an extra layer of protection against unauthorized access. In addition, remote workers sometimes have to share files over public internet connections. Encryption helps ensure that these files remain safe from being intercepted by hackers.

How to encrypt a file

File encryption uses algorithms designed to make it impossible to convert files into a readable format without the correct key. There are two main types of encryption methods. The first is symmetric encryption which only requires a single key to encrypt and decrypt data. This makes symmetric encryption faster and ideal for large volumes of information. On the other hand, asymmetric encryption uses a public key to encrypt the data and a private key to decrypt it. Asymmetric encryption works best for exchanging sensitive data over public or unsecured networks.

To encrypt a file, you can use built-in tools like Windows BitLocker or FileVault for macOS devices. Third-party applications also offer file encryption capabilities. Encryption key management is critical for end-users and businesses, as users may lose access to their own files if they lose their encryption keys.

Enhancing data security with file encryption

File encryption enables IT security experts to safeguard critical business data. Investing in endpoint security tools such as NinjaOne allows IT teams to leverage advanced encryption tools, monitor encryption status, and secure systems with total visibility of their IT environment.

NinjaOne centralizes all the tools you need to secure your endpoint devices, boosting efficiency.

What is the purpose of storage virtualization?

The primary purpose of storage virtualization is to streamline the management of storage resources and improve their efficiency.

• Boost efficiency

Storage virtualization enhances IT efficiency by centralizing the visibility of all storage resources for IT administrators. This makes it easier for IT teams to allocate, monitor, and secure storage from a single hub.

• Optimized storage space and performance

Storage virtualization pools resources, ensuring storage does not go underutilized across all devices in an IT infrastructure. This process also helps balance workloads across multiple storage devices, optimizing system performance and reducing bottlenecks.

• Scalability

With storage virtualization, IT administrators can easily add storage capacity in the future with minimal disruptions.

• Reduced costs

Businesses do not need to spend as much on expensive hardware and additional software for their storage needs.

How does storage virtualization work?

Storage virtualization begins with replicating physical storage as a virtual volume. The next step creates a virtual layer between physical storage devices and the servers that access them. This virtualization layer pools multiple physical disks into a single, logical storage volume. This consolidated storage pool can then be divided into smaller virtual disks, each appearing as a separate physical disk to the server. These logical storage blocks help redirect input/output (I/O) requests from operating systems or applications to the correct storage resources.

What is the most common type of storage virtualization?

The most common type of storage virtualization is network-based. Many businesses employ a storage area network (SAN), wherein a network device, like a server or smart switch, utilizes either the FC or ISCSI network protocols to connect several storage devices as a single virtual pool.

What are the risks of storage virtualization?

• Performance

If the virtualization layer isn’t properly optimized, it can introduce latency in I/O operations, slowing down applications. Resource contention through centralization might also lead to bottlenecks if infrastructure isn’t scaled appropriately.

• Centralization risks

The hypervisor behind virtualized storage can become a single point of failure, which means any issues could disrupt access to all virtualized storage resources.

• Malware and ransomware

Centralized storage environments can become targets for hackers, who can use malware and ransomware to compromise virtualized storage systems. Proper access controls, encryption, and secure protocols need to be implemented to maintain a strong security posture.

Secure virtualized storage and data.

While storage virtualization optimizes a business’s data storage flexibility, IT teams need to consider potential security risks and take pro-active measures to ensure data integrity and security. This is why IT decision-makers should consider investing in the best virtual machine monitoring software to safeguard their data.

NinjaOne provides IT teams with full visibility and control over their IT infrastructure, allowing businesses to rely on scalable and secure virtualized data storage infrastructure.

There is a semantic nuance that needs to be clarified here. To deprecate something, in general, means to express disapproval of or to belittle something. Think, “She deprecated the comedy” or “Raine laughed at her self-deprecating joke.” However, this should be taken seriously in IT. Deprecation in IT does not mean that experts “disapprove” of or “belittle” a software, for example; rather, users are discouraged from utilizing deprecated elements because they are more susceptible to various security vulnerabilities.

What are some examples of deprecation in IT?

Computer programming

In software development, programming language features are deprecated when newer, more secure, and optimized alternatives become available. A well-known example of deprecation in programming is the transition from Java’s Thread.stop method.

The method was officially deprecated in Java 1.2 due to its unsafe behavior, such as causing corrupted objects or leaving resources in an inconsistent state. Despite its deprecation, some legacy systems still reply on the Thread.stop method, making updates necessary for modern compatibility and security.

Operating systems

Operating systems deprecate older functionalities to focus on modern improvements. For example, Microsoft deprecated Internet Explorer for the newer, safer Edge browser. As of June 2022, Internet Explorer—while functional—no longer receives updates or support.

IT management tools

This year, Microsoft announced the deprecation of Windows Server Update Services (WSUS), signaling a major shift in its approach to patch management and software updates. While WSUS remains widely used by many organizations, Microsoft is strongly encouraging a transition to modern solutions like Windows Update for Business or Microsoft Endpoint Manager. These alternatives offer enhanced efficiency, better compliance tools, and stronger security measures, ensuring organizations can meet the demands of evolving IT environments. You can also check out our list of the best alternatives to WSUS.

Software applications

Enterprise software frequently deprecates older versions or features to improve performance. For example, Adobe deprecated Flash Player in 2020 due to security vulnerabilities. To facilitate a smooth transition, Adobe released several resources to their customers encouraging them to look for alternatives, such as its Adobe Express.

Hardware

Hardware technologies also face deprecation as newer standards emerge. One example is the deprecation of VGA and DVI ports on laptops in favor of HDMI and DisplayPort.

Keep in mind that this is not an exhaustive list. You will find several other examples of deprecation in IT, including in cloud computing, web development, networking, and more.

One thing to notice, however, is that deprecated IT elements are not necessarily removed instantly. Users can continue using deprecated software or hardware for some time but are strongly encouraged to seek alternatives. This is because deprecated technologies are more vulnerable to security risks and no longer receive updates, improvements, or support, making them increasingly obsolete and less reliable over time.

Best practices for deprecating features

When you receive news from a software provider or hardware developer that they will soon be deprecating an IT element or some of its features, you needn’t worry. In most cases, deprecated features remain functional long after its newer, safer alternative is released.

That said, it’s wise to begin looking for options. Over time, deprecated features may stop working or start causing other issues that make their usage difficult. Deprecated IT elements are also much more vulnerable to cyberattacks, particularly malware.

Reviewing the documentation provided by software developers for deprecated features is also a good idea. This documentation helps you understand the reasons behind the change, the potential risks, and the steps needed to adapt. By staying informed, you can better protect your systems, plan for transitions, and ensure continuity in your workflows.
