Let's start the conversation by discussing best practices for managing our firewalls and routers, and essentially our networking gear as a whole. When it comes to managing firewall and router security, we will be focusing on three main areas: physical devices, running operating systems, and secure traffic rules.
The three areas of router security that must be maintained are physical security, operating system security, and router hardening.
Basic router security
Every router should have a strong password to help keep out the bad guys. Some new routers come with default passwords, but you should change these during setup. Creating a new, complex, unique password for your wireless router is easy. It should only take a couple of minutes.
When choosing from among WEP, WPA, WPA2 and WPA3 wireless security protocols, experts agree WPA3 is best for Wi-Fi security. As the most up-to-date wireless encryption protocol, WPA3 is the most secure choice. Some wireless APs do not support WPA3, however.
Some general threats to routers include (but are not limited to) unauthorized access, session hijacking, rerouting, masquerading, DoS, eavesdropping, and information theft.
Common network security threats include malicious software (malware), phishing schemes, Distributed Denial of Service (DDoS).
The most common types of wireless network attacks are the following: packet sniffing. rogue access points. Wi-Fi phishing and evil twins.
Wi-Fi Protected Access II (WPA2) — introduced in 2004 — remains the most popular wireless security protocol. It uses the Counter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP) based on the Advanced Encryption Standard (AES) encryption algorithm for stronger security measures.
Which wireless authentication method provides the highest level of security? WPA aims to provide stronger wireless data encryption than WEP. Wi-Fi Protected Access (WPA) is a security protocol and security certification program developed by the Wi-Fi Alliance to secure wireless computer networks.
It controls access to your home Wi-Fi network and through that all of your phones, tablets, laptops, and more. If someone else gains access to that network—whether a remote hacker or your next-door neighbor—it can be quick work to compromise those devices. With that in mind, it's essential to keep your router secure.
For example, a router with a firewall enabled can block malicious traffic from entering a network and protect devices connected to the network from malware and other cyber threats. Additionally, routers can also be configured to encrypt data being transmitted over the network, providing an added layer of security.
There are three primary areas or classifications of security controls. These include management security, operational security, and physical security controls.
Network security systems work at two levels: at the perimeter and inside the network. At the perimeter, security controls try to stop cyberthreats from entering the network.
Network Security involves access control, virus and antivirus software, application security, network analytics, types of network-related security (endpoint, web, wireless), firewalls, VPN encryption and more.
The common types of network security include Network Access Control, IT Security Policies, Application Security, Vulnerability Patch Management, Network Penetration Testing, Data Loss Prevention, Antivirus Software, Endpoint Detection And Response (EDR), Email Security, Wireless Security, IDS/IPS, Network Segmentation, ...
Perpetrators in network attacks tend to target network perimeters to gain access to internal systems. There are two main types of network attacks: passive and active.
The traditional information security objectives are confidentiality, integrity, and availability. Achieving these three objectives does not mean achieving security [1]. It is well known that a formal security policy is a prerequisite of security.
The performance of a network can be affected by various factors: the number of devices on the network. the bandwidth of the transmission medium. the type of network traffic.
