Internal Network Security Best Practices

Internal Network Security Best PracticesWhen creating an internal security plan, many companies focus on the external side without realizing that internal network security can also be a factor. In thinking about it, it makes sense to focus on network security within the company. Despite the fact that most of a company’s valuable information assets are found internally, the theory seems to be that most of the threats will come from the outside. This may not necessarily be the case. Here’s a look at the best practices companies can follow when creating their internal network security best practices:

Insure Proper Patch Management

Patches are unique pieces of software that are designed to update existing applications and software programs. This is beneficial because patches can fix bugs, security vulnerabilities, and other problems with software that could leave data insecure. It is up to company IT departments or the managed IT service provider to come up with a strategy that will insure that the patch management protocol is effective and timely.

Create and Enforce Password Protocols

Although passwords are designed to create a level of security that will protect sensitive information, they can also be easy to hack. IT departments should not only create a set of password guidelines and protocols for employees to follow, but they should also enforce these policies. When IT departments create these guidelines, they should also insure that they are compliant with industry guidelines, such as those created by HIPAA and the PCI-DSS guidelines.

Use an Effective Firewall

Typically, firewalls are used to create a security barrier between the internal network, which is where sensitive company assets are located, and an Internet source from the outside, which tends to be insecure. Failure to use a state of the art firewall to secure this barrier can impact your internal network security. Once vulnerability enters the system from the outside, it can be difficult to contain from within. Good internal security begins with an effective firewall.

Regulate Workstation Internet Use

While it may seem convenient to allow employee’s workstations to access the outside Internet connection, this can leave the company vulnerable to outside security threats, such as malware and viruses. Company workstations at the very least should have regulated Internet usage through techniques that limits access to only known good sites. Once a machine from within the company is controlled by a hacker or is infected with something malicious, it puts the rest of the company at risk.

Install Adequate Protection

Antivirus, antimalware, and antispyware software programs are typically looked at as a way to help companies cope with malicious threat contracted from the outside. However, these programs can help with internal security threats, as well. Care needs to be taken to insure that the best programs are installed on company machines to help control threats both internally and externally.

When assembling a companywide network security practices, it’s important to make sure that protocols are set up for the internal network, not just the external one. Contact Roan Solutions for more information on how to set up an effective internal network security protocol.
