Network Security

Top 11 Checklist for Network Security

Network security is a set of software and hardware solutions that will help you in stopping attackers from accessing your networks. The main aim of network security is to create a secure platform for programs, users, and devices.

Network security will prevent unauthorized access to data and assets. It will help you in protecting your network data and infrastructure from threats. You can use it for detecting and responding to software anomalies and suspicious user behavior.

Managing and setting up network tasks are going to be a complicated and time-consuming chore. Network admins mainly use network security tools for monitoring activity.

1. Security Gateway

A security gateway is a network device that acts as a protective barrier between a private network and the Internet. It is used to protect a network from external security threats and to control access to the network. The main function of a security gateway is to inspect incoming and outgoing network traffic and to enforce security policies. This can include tasks such as filtering traffic based on specific criteria, such as IP address or port number, and blocking or allowing traffic based on the security policies defined.

Security gateways can also include additional security features such as firewalls, intrusion detection and prevention systems (IDPS), and virtual private networks (VPNs). Firewalls can be used to block unauthorized access to a network and to control the flow of traffic between different parts of a network. IDPS systems can be used to detect and prevent intrusions and to alert network administrators of suspicious activity. VPNs can be used to securely connect remote users to a network and to encrypt network traffic to protect it from being intercepted.

In summary, security gateways are essential to protect networks from external security threats and to control access to the network. They provide a range of security features such as firewalls, intrusion detection and prevention systems, and virtual private networks, which can be used to protect against unauthorized access, network intrusions, and malicious software. Additionally, security gateways can also provide email and web filtering to protect against spam, malware, and phishing attacks.

2. Intrusion Protection Systems

Another important function of security gateway is to inspect and filter email traffic to protect the network from spam, malware, and phishing attacks. It can also include antimalware and antispam features to protect against malicious software and unwanted email messages. Additionally, security gateways can also provide secure web gateway functionality to protect web traffic from malicious websites and to control access to specific web sites.

3. Anti-Malware / Anti-Virus

Anti-Malware will help you in delivering services and processes safely. It will protect your network from these cyber threats:

  • DDoS attacks: DDoS attacks can slow down your entire network. Attackers can overwhelm your network with fake traffic. Thus, sometimes your entire servers can crash. Network security will protect your network from DDoS attacks.

  • Malware: Malware infections like worms, spyware, and ransomware can affect your system. Network security will protect your network from different malware.

  • Insider attacks: These types of attacks occur when your employees either intentionally or accidentally damage the network.

  • APT: APT or Advanced Persistent Threats attack is very harmful to your network. It can result in data leakage.

  • Vulnerability exploits: Attackers can target weak points in your applications, login portals, and devices.

4. Regular Auditing

Network admins must have a clear understanding of your network map and infrastructure. This will help them in setting up proper defenses. They should know about the models, configurations, and locations of the following network devices:

  • Firewalls

  • Switches

  • Cabling

  • Wireless access points

  • Ports

  • Routers

Your network admin should know about the devices that are connected to your network. They should know about the connectivity path of your network. Auditing and mapping will help you in identifying weak points in your network. Thus, you can focus on improving network performance, reliability, and safety.

5. Network Segmentation

You should segment your network into smaller subsystems. These subnetworks will operate separately. These subnetworks will have their own access rules and security controls. Network segmentation will ensure that attackers can’t move freely in your network. They might get access to some part of your network. However, they won’t get access to other parts of your network. This will help you in isolating the compromised systems.

6. Use Strong Passwords

If your employees are using weak passwords, then attackers can easily crack their passwords. They can use simple brute force attacks for guessing your employee’s password. Attackers will silently gain access to your network. Make sure that your employees are using strong and complex passwords. They should also change their password regularly.

You should also consider using a password manager. Password manager tools will help you in creating strong passwords. Your employees don’t need to worry about remembering and creating strong passwords.

7. Keep Your Software Up to Date

The latest patches and updates will help you in protecting your network from threats. You should use a patch management system for ensuring that all your network tools are up to date. If you are working with an MSP, then they will help you in updating all your network tools. Experienced MSPs like QuikTek will help you in managing software patches and updates. They will ensure that all the network tools are up to date.

8. Zero Trust Security

You can use zero-trust security architecture for restricting access to sensitive data. Users will only have access to the data that they need. If your users need access to more devices, then they can contact the network admin. This security policy will also help you in complying with data security and privacy laws like HIPAA, PCI, and GDPR.

9. Staff Awareness

Make sure that your employees know about their responsibilities and roles. They should act as the mainline of security defense. Thus, you should ensure that you are training your employees. They should know about social engineering attacks. This will protect your business from simple attacks. Make sure that they are not clicking on strange emails and pop-ups. This will help you in protecting your business from phishing attacks. You should ensure that they are only connecting with secure Wi-Fi networks. Make sure that they are never turning off anti-virus and firewall. If you have old accounts in your network, then you should delete them. Your employees should know about your network security practices. They should ensure that they are following these security practices. Make sure that they are turning off their laptops and computers when they are not using them. They should communicate with the IT team if something is not working properly. Make sure that your employees know about your security policies. This will ensure that they can follow these security policies.

10. Use Honeypots

Honeypots are fake data storages or subnetworks that your security teams can use. These honeypots are also known as decoys. The main of these network segments is to attract attackers. Your regular employees won’t have access to this area. If there is some activity in this network area, then someone else has access to your network. Honeypots will help your security team identify intruder activities. They can quickly analyze malicious patterns and tactics. Your security team can quickly find weak points in your network and system. It will distract attackers from real resources and servers.

11. QuikTek

Network security will help you in protecting your business from cyber threats. It will ensure that your IT operations are protected from attackers. You should focus on improving your network safety. The best way to achieve this is by working with a good MSSP. Experienced MSSPs like Quiktek can help you in protecting your network from attackers. They will help you in implementing the best network security controls. QuikTek will help you in protecting your business from costly downtime.
