Proxy server virus
Jan 19, 2017
As with everything else in life: so many network security options, so little budget. How do you know which one will best protect your network, users and devices? No need to agonize over endless hours of research, we’ve shortlisted the five critical elements of cyber security: firewalls, NAC, anti-virus software, proxy servers, and endpoint security.
Filtering out malware that might otherwise bury itself so deeply into the network that it cannot be removed is a pure gain for your network security. That is what a firewall is for. How can you be sure you have a firewall suited to your network? Test it for stability under tough traffic conditions. According to NSS Labs you should subject your firewall to traffic from several protocol randomizers and mutation tools. And at a maximum of 350Mbps and 60, 000 packets per second. Another test is to see if your firewall blocks a constant stream of attacks over time, while allowing most of the legitimate traffic and alerting the admin to the attack.
On the downside, employees pressured to get their jobs done, might turn a firewall off as if it slows down their computers. Only regular employee training and raising awareness to the importance of the firewall will help here.
Network Access Control
Network Access Control (NAC – sometimes AKA Network Administration Control), provides visibility and control for any user and any device in the corporate network. Utilizing its agentless technology, it can detect and profile any device on the corporate network in real time across all network layers; wired and wireless network, VPN, Virtual and Cloud.
It also employs an access-control policy that matches users and permissions. This policy also defines endpoint security via wired or wireless networks. NAC enables you to set a policy for every user or group of users. This means that once a NAC solution is deployed, your cyber security team have a much easier time controlling access to the network (denying access if necessary), thus protecting it. Some of the NAC solutions are deployed in a central location (on premise / cloud) and can see all of the network locations – whether headquarter or a remote branch.
