How Network Security Professionals Can Help You

Network security refers to authorization of a computer user to a network. Users are provided with an ID and a password that grants them access to the computer network. Each user will have access according to their authority. Network security also provides protection against outside intrusions. These include Firewalls, antivirus and network security scanners. These are policies and procedures that prevent occurrences of misuse, modification and any unauthorized use. Networks can be used in private companies, government agencies as well as any non-profit organizations. Other networks are open to public access and still require adequate network security.

Making use of the correct security management tools is dependent on the size of the network. An experienced IT manager is able to complete security management for any size network. Preventing malicious attacks on your network such as hacking and spamming is vital to the productivity and longevity of your IT systems. Having a freelance consultant and network security professional who focuses on countering passive attacks such as wiretapping, port scanning and idle scanning is paramount to efficient operating networks. Active attacks such as viruses, eavesdropping and data modification can be combatted by a top level IT manager. Smurf attack, Buffer Overflow, Phishing and Cyber-attacks are serious threats to all networks, yet effortlessly annihilated by a freelance IT network specialist.
