Strengthening PC Security with Windows Whitelisting

 

Windows Defender, the built-in antivirus tool in Windows, provides real-time protection against malware by scanning for suspicious activity and blocking known threats using an extensive virus definition database. However, no antivirus software can completely prevent users from unknowingly installing harmful programs. 

Just like the famous Trojan horse deception, malicious software often enters systems disguised as legitimate applications. To counter this risk, Windows offers a security feature called whitelisting, which restricts access to only approved programs. Whitelisting allows administrators to create a list of trusted applications. Any new program attempting to run is automatically blocked unless explicitly authorized. 

This feature is especially useful in environments where multiple users access the same device, such as workplaces, schools, or shared family computers. By implementing a whitelist, users cannot accidentally install or run malware-infected software, significantly reducing security risks. Additionally, whitelisting provides an extra layer of protection against emerging threats that may not yet be recognized by antivirus databases. 

To configure a whitelist in Windows, users can utilize the Local Security Policy tool, available in Windows 10 and 11 Pro and Enterprise editions. While this tool is not included by default in Windows Home versions, it can be manually integrated. Local Security Policy enables users to manage Applocker, a built-in Windows feature designed to enforce application control. 

Applocker functions by setting up rules, similar to how a firewall manages network access. Applocker supports both whitelisting and blacklisting. A blacklist allows all applications to run except those explicitly blocked. However, since thousands of new malware variants emerge daily, it is far more effective to configure a whitelist—permitting only pre-approved applications and blocking everything else. This approach ensures that unknown or unauthorized programs do not compromise system security. 

Microsoft previously provided Software Restriction Policies (SRP) to enforce similar controls, but this feature was disabled starting with Windows 11 22H2. For users seeking a simpler security solution, Windows also provides an option to limit installations to only Microsoft Store apps. This setting, found under Apps > Advanced settings for apps, ensures that users can only download and install verified applications. 

However, advanced users can bypass this restriction using winget, a command-line tool pre-installed in newer Windows versions that allows software installation outside the Microsoft Store. Implementing whitelisting is a proactive security measure that helps safeguard PCs against unauthorized software installations. 

While Windows Defender effectively protects against known threats, adding a whitelist further reduces the risk of malware infections, accidental downloads, and security breaches caused by human error. By taking control of which programs can run on a system, users can enhance security and prevent potential cyber threats from gaining access.

These Four Basic PC Essentials Will Protect You From Hacking Attacks


There was a time when the internet could be considered safe, if the users were careful. Gone are the days, safe internet seems like a distant dream. It is not a user's fault when the data is leaked, passwords are compromised, and malware makes easy prey. 

Online attacks are a common thing in 2025. The rising AI use has contributed to cyberattacks with faster speed and advanced features, the change is unlikely to slow down. To help readers, this blog outlines the basics of digital safety. 

Antivirus

A good antivirus in your system helps you from malware, ransomware, phishing sites, and other major threats. 

For starters, having Microsoft’s built-in Windows Security antivirus is a must (it is usually active in the default settings, unless you have changed it). Microsoft antivirus is reliable and runs without being nosy in the background.

You can also purchase paid antivirus software, which provides an extra security and additional features, in an all-in-one single interface.

Password manager

A password manager is the spine of login security, whether an independent service, or a part of antivirus software, to protect login credentials across the web. In addition they also lower the chances of your data getting saved on the web.

A simple example: to maintain privacy, keep all the credit card info in your password manager, instead of allowing shopping websites to store sensitive details. 

You'll be comparatively safer in case a threat actor gets unauthorized access to your account and tries to scam you.

Two-factor authentication 

In today's digital world, just a standalone password isn't a safe bet to protect you from attackers. Two-factor authentication (2FA) or multi-factor authentication provides an extra security layer before users can access their account. For instance, if a hacker has your login credentials, trying to access your account, they won't have all the details for signing in. 

A safer option for users (if possible) is to use 2FA via app-generated one-time codes; these are safer than codes sent through SMS, which can be intercepted. 

Passkeys

If passwords and 2FA feel like a headache, you can use your phone or PC as a security option, through a passkey.

Passkeys are easy, fast, and simple; you don't have to remember them; you just store them on your device. Unlike passwords, passkeys are linked to the device you've saved them on, this prevents them from getting stolen or misused by hackers. You're done by just using PIN or biometric authentication to allow a passkey use.

Privacy Concerns Rise Over Antivirus Data Collection

 


To maintain the security of their devices from cyberattacks, users rely critically on their operating systems and trusted anti-virus programs, which are among the most widely used internet security solutions. Well-established operating systems and reputable cybersecurity software need to provide users with regular updates.

As a result of these updates, security flaws in your system are fixed and security programs are upgraded, enhancing your system's protection, and preventing cybercriminals from exploiting vulnerabilities to install malicious software such as malware or spyware. Third-party applications, on the other hand, carry a larger security risk, as they may lack rigorous protection measures. In most cases, modern antivirus programs, firewalls, and other security measures will detect and block any potentially harmful programs. 

The security system will usually generate an alert when, as a result of an unauthorized or suspicious application trying to install on the device, users can take precautions to keep their devices safe. In the context of privacy, an individual is referred to as a person who has the right to remain free from unwarranted monitoring, surveillance, or interception. The concept of gathering data is not new; traditionally data was collected by traditional methods based on paper. 

It has also been proven that by making use of technological advancements, data can now be gathered through automated, computer-driven processes, providing vast amounts of information and analytical information for a variety of purposes every minute from millions of individuals in the world. Keeping a person's privacy is a fundamental right that is recognized as essential to their autonomy and their ability to protect their data. 

The need to safeguard this right is becoming increasingly important in the digital age because of the widespread collection and use of personal information, raising significant concerns about privacy and individual liberties. This evaluation included all of PCMag's Editors' Choices for antivirus and security suites, except AVG AntiVirus Free, which has been around for several years. However, since Avast acquired AVG in 2016, both have been using the same antivirus engine for several years now, so it is less necessary for them to be evaluated separately. 

It was determined that each piece of security software was evaluated based on five key factors: Data Collection, Data Sharing, Accessibility, Software & Process Control, and Transparency, of which a great deal of emphasis should be placed on Data Collection and Data Sharing. This assessment was performed by installing each antivirus program on a test system with network monitoring tools, which were then examined for their functionality and what data was transmitted to the company's parent company as a result of the assessment. In addition, the End User License Agreements (EULAs) for each product were carefully reviewed to determine if they disclosed what kind and how much data was collected. 

A comprehensive questionnaire was also sent to security companies to provide further insights into their capabilities beyond the technical analysis and contractual review. There may be discrepancies between the stated policies of a business and the actual details of its network activities, which can adversely affect its overall score. Some vendors declined to answer specific questions because there was a security concern. 

Moreover, the study highlights that while some data collection-such as payment information for licensing purposes-must be collected, reducing the amount of collected data generally results in a higher Data Collection score, a result that the study findings can explain. The collecting of data from individuals can provide valuable insights into their preferences and interests, for example, using information from food delivery apps can reveal a user's favourite dishes and the frequency with which they order food. 

In the same vein, it is common for targeted advertisements to be delivered using data derived from search queries, shopping histories, location tracking, and other digital interactions. Using data such as this helps businesses boost sales, develop products, conduct market analysis, optimize user experiences, and improve various functions within their organizations. It is data-driven analytics that is responsible for bringing us personalized advertisements, biometric authentication of employees, and content recommendations on streaming platforms such as Netflix and Amazon Prime.

Moreover, athletes' performance metrics in the field of sports are monitored and compared to previous records to determine progress and areas for improvement. It is a fact that systematic data collection and analysis are key to the development and advancement of the digital ecosystem. By doing so, businesses and industries can operate more efficiently, while providing their customers with better experiences. 

As part of the evaluation of these companies, it was also necessary to assess their ability to manage the data they collect as well as their ability to make the information they collect available to people. This information has an important role to play in ensuring consumer safety and freedom of choice. As a whole, companies that provide clear, concise language in their End User License Agreements (EULA) and privacy policies will receive higher scores for accessibility. 

Furthermore, if those companies provide a comprehensive FAQ that explains what data is collected and why it's used, they will further increase their marks. About three-quarters of the participants in the survey participating in the survey responded to the survey, constituting a significant share of those who received acknowledgement based on the transparency they demonstrated. The more detailed the answers, the greater the score was. Furthermore, the availability of third-party audits significantly influenced the rating. 

Even thought a company may handle its personal data with transparency and diligence, any security vulnerabilities introduced by its partners can undermine the company's efforts. As part of this study, researchers also examined the security protocols of the companies' third-party cloud storage services. Companies that have implemented bug bounty programs, which reward users for identifying and reporting security flaws, received a higher score in this category than those that did not. The possibility exists that a security company could be asked to provide data it has gathered on specific users by a government authority. 

Different jurisdictions have their own unique legal frameworks regarding this, so it is imperative to have an understanding of the location of the data. The General Data Protection Regulation (GDPR) in particular enforces a strict set of privacy protections, which are not only applicable to data that is stored within the European Union (EU) but also to data that concerns EU residents, regardless of where it may be stored. 

Nine of the companies that participated in the survey declined to disclose where their server farms are located. Of those that did provide answers, three chose to keep their data only within the EU, five chose to store the data in both the EU and the US, and two maintained their data somewhere within the US and India. Despite this, Kaspersky has stated that it stores data in several different parts of the world, including Europe, Canada, the United States, and Russia. In some cases, government agencies may even instruct security companies to issue a "special" update to a specific user ID to monitor the activities of certain suspects of terrorist activity. 

In response to a question regarding such practices, the Indian company eScan confirmed that they are involved in such activities, as did McAfee and Microsoft. Eleven of the companies that responded affirmed that they do not distribute targeted updates of this nature. Others chose not to respond, raising concerns about transparency in the process. `

How to Enhance Your Windows Security with Memory Integrity

 

Windows Security, the antivirus program built into Microsoft’s operating system, is generally sufficient for most users. It provides a decent level of protection against various threats, but a few important features, like Memory Integrity, remain turned off by default. This setting is crucial as it protects your system’s memory from malicious software that attempts to exploit Windows drivers, potentially taking control of your PC.

When you enable Memory Integrity, it activates Virtualization Based Security (VBS). This feature separates the code verification process from the operating system, creating a secure environment and adding an additional layer of protection. Essentially, VBS ensures that any code executed on your system is thoroughly checked, preventing malicious programs from sneaking through Windows’ defenses.

However, Microsoft disables Memory Integrity by default to maintain smoother app performance. Some applications may not function properly with this feature on, as the extra layer of security can interfere with the way certain programs execute code. For users who prioritize app performance over security, this trade-off may seem appealing.

But for those concerned about malicious attacks, enabling Memory Integrity is a smart choice. It prevents malware from bypassing the usual system checks, providing peace of mind when dealing with potential security threats. On older PCs, though, you might notice a slight reduction in performance once Memory Integrity is activated.

Curious to see how your system handles this extra protection? Enabling and disabling Memory Integrity is a simple process. First, type “Windows Security” into the search bar or Start menu. Under Device Security, you may see a notification if Memory Integrity is off. Click Core Isolation, then toggle Memory Integrity on. To deactivate it, return to the same settings and flip the switch off.

It’s not just Memory Integrity that comes disabled by default in Windows. Microsoft leaves certain protections off to strike a balance between security and user experience. Another useful feature you can enable is ransomware protection, which safeguards specific folders and prevents unauthorized apps from locking you out of your data. Similarly, you can turn on advanced app screening to block potentially harmful programs.

While leaving Memory Integrity and other protections off can offer a smoother computing experience, activating them significantly strengthens your system’s defenses against cyber threats. It’s a choice between performance and security, but for those prioritizing protection, flipping these settings on is an easy step towards a safer PC.

Understanding Hardware and Software in Cybersecurity


 

When it comes to cybersecurity, both hardware and software play crucial roles in keeping your devices safe. Here's a simple breakdown of what each one does and how they work together to protect your information.

Hardware: The Physical Parts

Hardware includes the physical components of a computer, like the processor, hard drives, RAM, and motherboard. These are the parts you can actually touch. In cybersecurity, hardware security involves devices like biometric scanners (such as fingerprint and iris scanners) and Trusted Platform Modules (TPMs), which securely store sensitive information like passwords. Ensuring physical security, such as keeping servers in a locked room, is also important to prevent unauthorised access.

Software: The Programs and Applications

Software consists of the programs and instructions that run on the hardware. This includes operating systems, applications, and stored data. Software security involves tools like firewalls, antivirus programs, encryption software, and intrusion detection systems. These tools help protect against cyber threats like malware, phishing attacks, and ransomware. Regular updates are necessary to keep these tools effective against new and continuously growing threats.

How They Work Together in Cybersecurity

Both hardware and software are essential for a strong cybersecurity defence. Hardware provides a foundation for physical security. For example, biometric scanners verify the identity of users, and TPMs store critical data securely. 

Software actively defends against online threats. Firewalls block unauthorised access to networks, antivirus programs detect and remove malicious software, and encryption software protects data by making it unreadable to unauthorised users. Intrusion detection systems monitor network activity and respond to suspicious behaviour.

Building a Strong Cybersecurity Strategy

To create a comprehensive cybersecurity strategy, you need to combine both hardware and software measures. Hardware ensures that your devices are physically secure, while software protects against digital threats. Together, they form a defence system that protects your information from being stolen, damaged, or accessed without permission.

Maintaining both physical and digital security is key. This means regularly updating your software and ensuring the physical safety of your hardware. By doing this, you can build a robust cybersecurity strategy that adapts to new threats and keeps your devices and data safe.

We need to be up to date with the roles of hardware and software in cybersecurity to develop effective strategies to protect against various threats. Both are vital in safeguarding your digital life, providing a layered defence that ensures the security and integrity of your data and systems.

Global Outage Caused by Anti-Virus Update from Crowdstrike

 

A recent update from the anti-virus firm Crowdstrike has led to a global outage affecting millions of Windows users. The incident is being termed one of the most extensive outages ever, impacting numerous services and companies worldwide. Crowdstrike, a company many may not have heard of before, inadvertently caused this disruption with a problematic update to its Falcon virus scanner. The update led to widespread reports of the infamous Blue Screen of Death (BSOD) on computers running Windows. 

Microsoft quickly clarified that the issue was due to a third-party problem, absolving itself of direct responsibility. Users of Apple and Linux systems were unaffected, which brought some relief to those communities. Crowdstrike has since released a fix for the issue, but the recovery process remains cumbersome. IT professionals have noted that each affected machine requires a manual reboot in safe mode to restore normal operations. This task is complicated by the physical accessibility of the devices, making the resolution process even more challenging. There is currently no indication that the issue was caused by malicious intent or that any data has been compromised. 

Nonetheless, this incident highlights the crucial importance of staying updated with software patches, albeit with a note of caution. The cybersecurity community continues to stress the necessity of regular updates while acknowledging the occasional risks involved. Crowdstrike’s initial response fell short of an apology, which drew significant criticism online. However, CEO George Kurtz later issued a public apology via NBC News, expressing deep regret for the disruption caused to customers, travelers, and affected companies. This gesture, while somewhat late, was an important step in addressing the public’s concerns. This episode serves as a stark reminder of our heavy reliance on remotely managed devices and the vulnerability that comes with it. 

Despite robust systems in place to catch most issues, some problems, like this one, slip through the cracks. The timing of the update, which was pushed out on a Friday, compounded the difficulties, as fewer staff are typically available over the weekend to address such crises. For Crowdstrike customers, detailed instructions for the fix are available on the company’s support website. Many companies with dedicated IT teams are likely coordinating their responses to ensure a swift resolution. 

Unlike many outages that resolve themselves quickly, this incident will take days, if not longer, to fully mend, illustrating the significant impact of a single flawed update in our interconnected digital world.
