The most common antivirus product is a disk scanner, which runs through the contents of all files, disks, and directories, identifying potential threats, and quarantining them. Similarly, you could benefit from running a start-up scanner, which performs a quick check of your system files and boot sectors when you turn on your computer. The purpose of this is to catch and terminate boot sector viruses, before they are able to take effect.
Another approach to virus protection is to install software which runs quietly in the background. These products use behaviour-based detection, which monitors for “virus-like activity” and intercepts it. This can be used in conjunction with a memory-resident scanner, which is configured to perform targeted scans based on particular triggers, such as running a program or executing a file.
Keep your system up to date
Once your security system is up to date, you can fine-tune it by testing for weaknesses. Software development platforms, such as the Metasploit Framework, allow you to develop exploit modules and similar tools for testing the limits of your system. By identifying vulnerabilities, you can continuously make improvements, and maintain a high standard of security throughout your organisation.
Of course, no amount of security can account for human error, so the final, crucial step in securing your network is to ensure all employees have a good understanding of cyber security, and appropriate use of work computers. In particular, remind everyone to beware of links in emails and other messages, even if the sender appears to be someone they know.
It can seem like a lot to take in, but once you make these initial changes, it is a simple thing to stay up-to-date, and informed. It is never worth compromising on internet security, as it puts not only your data and devices at risk, but also the trust of your clients, and the reputation of your business. However, a comprehensive security strategy can put your mind at ease, while constantly preparing you for the ever-changing future of malware.
