Network Security Fundamentals
Network security starts with understanding the basic concepts behind protecting networks, devices, users and data. With our Network Security Fundamentals Cheat Sheet, you can quickly review important topics such as the network attacks, threats, vulnerabilities, risks, security controls and defense-in-depth. These fundamentals are useful for both network security certification studies and daily network security operations.
Network Attacks and Threats
Network engineers should understand not only how networks work, but also how they can be attacked by malicious systems and people. IPCisco Network Attacks Cheat Sheets cover common attacks such as DoS and DDoS attacks, Man-in-the-Middle attacks, spoofing, MAC flooding, VLAN hopping, DHCP attacks and other common network threats. Knowing these attacks will also help you understand why different network security mechanisms are used.
Cisco Access Control and Layer 2 Security
ACLs, Port Security, DHCP Snooping, Dynamic ARP Inspection and 802.1X are important technologies used to control and protect network access. With IPCisco Cisco Security Cheat Sheets, you can quickly review how these technologies work and where we use them. We will also focus on how we configure these technologies on Cisco devices.
AAA, RADIUS and TACACS+
Authentication, Authorization and Accounting are important parts of secure network access and network device management. Our AAA Cheat Sheet covers AAA concepts together with RADIUS and TACACS+, helping you quickly review their roles, differences and common use cases. This is especially useful when studying Cisco security topics and secure network management.
VPN, IPsec and Firewall Security
VPNs and IPsec provide secure communication over untrusted networks, while firewalls control traffic between networks and security zones. Here, VPN, IPsec and Firewall Cheat Sheets provide visual quick references for important concepts such as VPN types, tunnels, encryption, IKE, ESP, security associations, firewall types, security zones and traffic filtering. You can quickly check the related technologies with these network security cheat sheets.
IDS, IPS and Network Device Hardening
Protecting a network also requires detecting malicious activity and securing the network devices themselves. IDS and IPS technologies help identify or prevent suspicious traffic, while Device Hardening reduces the attack surface of routers, switches and other network devices. Our network security cheat sheets provide quick references for also these technologies. Here, we will cover secure management, SSH, AAA, unused services and ports, logging and other important hardening practices.
