A computer virus, similar to those that infect humans, replicates itself once on your computer by modifying other vital programs and processes all the while inserting its code. These viruses cause billions of dollars in damage each year, often due to the amount of time spent fixing the infected computers and ensuring that they cannot be attacked again through the use of antivirus.
Antivirus is software removes computer viruses from your computer and prevents further infections by protecting your computer from a multitude of complex and varied attack vectors.
Antivirus is a broader term for software that eradicates computer viruses but internet security focuses solely on securing your browser and network while you browse the web. It is becoming commonplace for websites to be secured from their hosting services but it is still crucial to protect yourself and your network against possible intrusions locally. Internet security can come in the form of browser security, network security, or a mix of both that maintains a disruption-free state on your computer and connected networks.
Network Security Management
Network security management is a series of policies and practices that can be implemented to monitor and prevent possible unapproved access to computer networks. Network security management is vital because it maintains a network’s stability and security from a central source, usually a network administrator.
This network security is not just for businesses. Home network security is important because once a computer are accessed on a network, other computers are compromised as well. Network security begins with authentication (i.e., use of a username and password) and then is strengthened with the use of a firewall and intrusion prevention system to handle any other possible threats.
Business Network Security
While it is important for home networks to maintain a secure state, businesses stand to lose more from a lack of business network security due to the logging and storing of sensitive information. As seen recently with companies like Target and Equifax, the smallest vulnerability in a network can cost a company not only thousands to millions of dollars in damages but also lost revenue due tarnishing of its reputation. These breaches, while costly, could have been prevented with through the use of increased network security measures.
The most common security measures for a business to employ are firewalls, authentication, and the use of a VPN but these can all still be susceptible. It’s important to increase the usefulness of these security measures by creating a login for your firewall, switching to two-step authentication, and ensuring that the VPN’s connection are double encrypted and maintains no log practices. These minor adjustments to business network security can further protect you and your business against the possible losses from malicious outside attacks.
