3 Levels of Corporate Network Security

As cyberthreats are constantly evolving in complexity and volume, the battle against them implies ‘spreading’ the protection across all the systems in the corporate network – servers, databases, services, installed software, etc. What’s more, attention should be paid to ensuring that the company’s employees understand and follow cybersecurity principles, and will not (un)intentionally compromise the corporate network security with their actions.

However, cybersecurity measures applied inside the organization may differ depending on the company’s size, its financial capabilities, the industry it operates in (regulated or non-regulated), the information it has to deal with in the course of business activities, etc.

The minimum of cybersecurity measures essential for the implementation is a properly configured firewall protection working together with regularly updated antivirus software. Firewalls scan network traffic to detect anomalous packets or packet fragments. Antiviruses ensure protection from such cyberthreats as ransomware, worms, spyware, etc. by checking each file the employees open or download from the internet or other sources.

To apply these security measures, there’s no need in organizing a separate cybersecurity department. A company’s IT department can take responsibility for this, as implementing firewall protection, installing antivirus software and continuously maintaining their performance does not require cybersecurity-related skills.

Nevertheless, the protection level of a corporate network should be regularly checked. Conducting vulnerability assessment and penetration testing annually is enough for a small organization carrying out their business in a non-regulated industry. These cybersecurity services performed on an annual basis won’t result in heavy expenses for a company with a limited budget. At the same time, these activities can help system administrators to stay aware of occurring security weaknesses inside the
company’s network.

Learning the most common causes of DNS issues and the best methods for fixing them can help you get back online with minimal effort. Essentially the DNS translates the domain names we use to access websites into IP addresses, which is what your computer actually uses to access the website. In most cases, a DNS problem is easy to fix Network Problems In many cases, an error attributed to DNS could be a simple connection problem (especially if you're connecting wirelessly using a laptop) that doesn't really relate to the DNS at all. Before blaming DNS errors, go to your "Network and Sharing Center" and run the troubleshooter.

How to disable SmartScreen in Windows 10 Creators Update

Windows 10 Creators Update introduced a number of changes to the user interface, so disabling Smart Screen can be a bit confusing. In this article, we'll see how to properly disable SmartScreen in it. The SmartScreen filter is a technology which was initially designed for Internet Explorer to protect users from malicious websites and web applications. It was integrated with IE8 and IE9 (as the successor to IE7's Phishing filter). Starting with Windows 8, Microsoft implemented Internet Explorer's SmartScreen feature directly into the operating system so files are screened for being potentially harmful. SmartScreen is also integrated for Windows Store apps. If enabled, the Windows SmartScreen filter sends information about every application you download and run to Microsoft’s servers, where that information will be analyzed and compared with their malicious apps database. If Windows gets a negative feedback about the app from the server, it will prevent you from running ...
