Securing a network is an administrator’s main priority, and with good reason. Insecure networks are open to infiltration by viruses, malware, and hackers. A dedicated threat can even bring down an entire system, costing a company time and resources. As important as it is, security is not difficult to achieve. Neither is it an expensive undertaking. Here are eight simple things that Linux for network engineers can improve a network’s security. 1) Migrate to Linux The fact that Linux experiences fewer security issues than Windows is very well-known. Migrating some desktops from Windows to Linux is an easy yet effective way of improving network security. Users who do not rely on proprietary Windows applications can migrate first. But to ensure that they continue accessing Webmail, OWA should be set up in place of Exchange. 2) Restrict the Installation of Software Users who install software at will expose the whole network to viruses and malware. Thus, only administrators should conduct installations. And if users must install anything, it must be with their administrator’s approval. Yes, they will find this frustrating but it is necessary for network security. And it pays off dividends in the long run.
