Network Security Best Practices

The IT security world today is faced with threats that are quickly changing and hitting networks from all points of entry. Without proper security policies in place, your network can easily be compromised by greedy cyber-criminals from all points of the globe. Businesses now house the majority of their sensitive data online, so if it gets into the wrong hands, the information belonging to customers and employees can easily be stolen and used for financial gain. Below we discuss network security best practices to protect your website and network from vulnerabilities that lead to cyber-attacks.


Develop Company Network Security Policies

Your business should have a clearly laid out security policy that is easy to read. Even if it starts with just one page, security practices should be outlined with basic rules. These rules must include guidelines for passwords and user access, and policies for backing up confidential customer records and financial data.


Develop Removable Media Policies

Your company should also have policies restricting the use of removable media. Items like external hard drives, USB drives, thumb drives and any other writeable media are easy tools to facilitate security breaches as they enter or leave your network.


Deploy Company-Wide Encryption

A majority of the identity theft that has occurred has happened because of systems that were not encrypted. Take a look at all types of electronic communication used within the company. Everything from emails to thumb drives to file transfers need encryption, as well as stored customer records. Encryption is critical to guarding sensitive data and stopping data loss in the event of theft, a security breach or equipment loss.


Assess Websites for Vulnerabilities Frequently

Custom Web application code changes frequently. Every new line of code has the potential of allowing new vulnerabilities into a website. If a website does not change, there is still the chance that the Web application security industry has. It is a best network security practice to assess websites as often as on a weekly basis to have a constant level of protection from hackers. Assessing the web sites on a regular basis lets you find and fix vulnerabilities before the cyber-criminals have a chance to exploit them. Digital certificates should be used to sign all of your sites and be obtained from trusted authorities.


Layer Endpoint Network Security

It is recommended that companies use a layered product to prevent malware infections on devices. It is important to use antivirus software, but that is unfortunately not enough. The total approach to endpoint protection includes intrusion detection and a personal firewall on top of antivirus software. Email servers must have spam filters to eliminate junk mail and reduce phishing scams.


Maintain Current Software, Security Patches and Updates

The more current your software is, the more secure it is. Always keep your software updated with the application of the latest patches and service packs. There are particular antivirus programs that update on a seemingly daily basis. If you turn off automatic updating settings, be sure to set up a regular scan for your systems.
