Online Security is a type of computer security that establishes rules and measures to protect organizations against internet-borne threats such as viruses, spam and hackers. It also supports a strong, healthy firewall.

The cornerstone of online security involves the authorization of access to data in a network, which is controlled by the network administrator. Online security involves both public and private computer networks that are used in the course of business deals, e-commerce, government transactions and more.

While small businesses may only need basic security, large companies generally require high maintenance and advanced software and hardware to prevent malicious attacks from inflicting damage.

Data centers offer a variety of online security defenses to help their clients prevent web attacks, including:

• Managed firewalls
• Web application firewalls
• Log management
• Intrusion detection/protection (IDS/IPS)
• Web security
• Managed VPN
• E-mail security
• Vulnerability scanning and penetration testing
• VSS for multitenant virtual environments
