Cyber-attacks have increasingly become more bold and evasive. To counter the threat posed, organizations need to adhere to some well-defined network security best practices. Unfortunately, buying the best network security firewall is not an end in itself. To start with, there will be a need for capacity building to ensure that the IT security staff are equipped to respond to and handle cybersecurity threats.

Secondly, companies have to avail of resources including specialized gadgets and appliances that help in maintaining network security. For example, Sophos Firewall, Kaspersky endpoint for business, etc. On the other hand, the IT Security staff have to ensure that firewall protection services are well configured. Moreover, all the subscription services should be up to date. Otherwise, the network will be left vulnerable if the subscription-based protection modules remain unsubscribed if they expired.

Network security best practices that keep you protected

Install a unified threat management firewall

For a start, network security begins with the firewall system installed in place. Likewise, installing a firewall system with unified threat management capability is a step in the right direction. The firewall system should be able to offer intrusion prevention, email protection, and sandboxing. Other important firewall services include web and application security, webserver protection and endpoint protection.

Network Security Best Practices

LAN segmentation

Most network attacks get propagated through lateral movement. The attacks become more severe if the main LAN network is not segmented into smaller independent LANs. More importantly, by segmenting the corporate network, attacks will be stopped from spreading.

An ideal LAN structure consists of several subnets and VLANs for different sections and departments. As a matter of fact, most network security firewalls allowing the creation of network zones. For this reason, increased visibility into the network can be achieved through the zoning.

Enable email scanning service

All emails coming in through the gateway must go through a filter. The filter will scan the email header, the body plus any attachments. The emails that meet the protection threshold set will be delivered to the rightful recipients. On the other hand, all emails with suspicious headers or attachments will be quarantined for further scanning before being released. What is more, those emails that out rightly fall below the set standard will be dropped at the gateway level.

Fixing software vulnerabilities

Hackers usually exploit the vulnerabilities found in software and other applications. These vulnerabilities act as the backdoor through which attackers gain access to private networks. Nonetheless, these software vulnerabilities can be spotted and fixed. To begin with, the software and applications used should be genuine and licensed. Secondly, all updates from the software or app developer should be installed religiously as released.

Synchronize endpoint protection with network firewall

Synchronization between different IT security platforms creates the much-needed synergy in fighting cybersecurity threats. Therefore, the endpoint security software will be updating the network firewall of suspicious activities associated with specific users or devices. In the unlikely event that a device gets infected, the firewall system will automatically isolate it. Manual cleanup will be initiated and the endpoint will be reconnected back to the network only when all the threats have been neutralized.

The use of strong passwords

Indeed, weak passwords easily fall prey to brute force attacks. Attackers usually start with brute force attack tools to steal passwords for various network resources. Particularly, where a trend in password usage can be spotted. Be that as it may, it is advisable that employees use strong passwords. By way of example, combining uppercase and lowercase letters and special characters and numbers make strong passwords.

Implementing all the above measures can actually help organizations to stay protected from nearly all cyber-related attacks. In as much as cybersecurity is a real threat, organizations that get well prepared are rarely targeted. In fact, attackers can tell whether an organization has in place advanced security systems or not. Hence, if breaking the security barrier proves to be a great hassle, attackers would not bother wasting time on trying to break into a well-secured resource.

As professional cybersecurity consultants, companies can stay protected from Ransomware attacks by implementing the above network security best practices. Diligence to a well-laid cybersecurity strategy will not only protect the endpoints but also the IP telephony infrastructure.
