Network Security

1. You absolutely must protect your internal corporate network and perimeter networks from intruders and malware using network firewalls (software and/or appliances), VPNs (virtual private networks), IDSs (intrusion detection systems), as well as web and content filtering for your enterprise. Network security is a constantly continuing and dynamic process.

• Network security includes the following four steps:

Secure: Lock your networks with a combination of authentication, encryption, firewalls, and continuous patching of system vulnerabilities;

1. Examine: To maintain a secure network, you have to regularly monitor the state of security mechanisms, readiness, and incident handling procedures. Network vulnerability scanners from a number of reputable vendors will proactively locate areas of weakness, and IDSs can alert and respond to security events when they occur. Your organization can get high visibility of the network data stream and the security condition of the network using emerging security solutions;
2. Test: Equally as vital as network examination and assessment is testing. Without adequate testing of the security solutions, it's tough to know about new threats and attacks. The hacker community is an ever-changing continuum with menacing designs on your systems and data. You can perform this testing yourself or you can outsource it to a third party;
3. Enhance: Use the information gathered from the Examine and Test phases to constantly enhance and improve the corporate security implementation and modify the security policy as new vulnerabilities and risks are identified and the business model changes.
4. It's much more effective to address security with a sound proactive strategy as opposed to a reactive and uncoordinated approach. A strategic methodology allows you to control security at the business level and at every area of vulnerability. This layers of security implementation provides a technique for each area of security in your business. Your security team can pick and choose which layers to concentrate on for your particular business needs. You can effectively prioritize specific areas for immediate action, and then easily add security mechanisms at any layer at any time as your business changes and your security assessment dictates.
