  • SSH Encryption

    SSH stands for Secure Shell and is mostly used on UDP port 22. SSH is a protocol that is used to remotely access network devices such as routers, switches, APs and many more devices. These SSH sessions are mostly for management and provide a convenient way to manage and verify configuration states without having to…

  • Syslog Monitoring Locations

    Hi, today I am going to dive into the syslog monitoring locations. Syslog is one of the major logging protocols that allow network devices such as routers, switches, APs, or firewalls to generate, store, and send event notifications to a centralized logging or external server. Syslog is versatile in where these messages can be displayed…

  • Syslog

    Today I am going to talk about syslog. Syslog is a UDP (port 514) protocol that is the standard for logging where it allows network devices to generate, store and send event based notifications to a centralized server. If you have been doing any type of labs, you have definitely seen a syslog message as…

  • SNMP Security

    In recent blogs, I’ve written about SNMP and how it works. SNMP is a great protocol for monitoring network devices on an IP network. There are currently 3 versions of SNMP and all of them have different ways of implementing security. The latest version of SNMP which is version 3 is the most secure, with…

  • SNMP Read/Write Operations

    SNMP is a network management protocol used to manage and monitor network devices on an IP network. It is an application layer protocol that is run in an agent-manager model. SNMP communication is initiated by both the manager and the agent, depending on the type of operation. Today I am going to discuss the various…

  • SNMP

    Today I am going to talk about SNMP which stands for Simple Network Management Protocol. This is an application-layer protocol that is used to monitor, configure, and manage network devices on an IP network. This protocol is an agent-manager model, where both the agent and the manager communicate to each other exchanging information that is…

  • DHCP Release/Renew

    DHCP is a protocol used to automatically assign IP addresses to devices on a network. There are two DHCP features that I want to talk about today which are “release” and “renew.”  Release- When a client sends a DHCP release, the host is prematurely relinquishing its IP address lease. When IP address leases are assigned…

  • DHCP Relay Agent

    DHCP is a network management protocol that is used to automatically assign IP addresses to devices on a local network. This is done through broadcasting DHCP messages so the DHCP server can respond. But what if the DHCP server is located on another subnet? This is where a DHCP relay agent takes over. Relay Agent–…

  • DHCP DORA Process

    DORA- Today I am going to talk about DHCP which stands for Dynamic Host Configuration Protocol. DHCP is a network management protocol that is used to dynamically assign IP addresses and other network configuration parameters to devices automatically. DHCP reduces manually having to assign device after device. DHCP is stateful, meaning that every IP address…
