It's About Time – The Importance of NTP for Networks
by PivIT Global on Sep 13, 2022 7:04:00 AM
There is no doubt that time is money, and time is of utmost importance when dealing with network devices. An incorrect time running on network devices almost always reflects negatively on the stability and overall network behavior. Many services used daily heavily depend on the correc …
The Importance of Layer 3 Redundancy: Understanding HSRP – Pt. 2
by PivIT Global on Aug 16, 2022 7:11:00 AM
The Hot Standby Router Protocol (HSRP) is a Cisco proprietary redundancy protocol. It allows several Layer 3 switches or routers to work together in an HSRP group and appear as a single virtual device to endpoints. Because of this approach, endpoints always have a functional default g …

Network redundancy provides multiple paths for traffic so that network communications remain functional even during a failure. A network failure can occur due to a faulty device/link or a network attack (e.g., DDoS, man-in-the-middle attacks, ARP spoofing, etc.). Relying on just one d …
The Essentials of ARP Protocol & How To Protect Against Spoofing Attacks
by PivIT Global on Jun 28, 2022 7:10:00 AM
No matter how strong your security measures are, there is an attacker working to get through them. Treating this as inevitable is key to keeping your data safe and secure. In our two-part packet delivery process blogs here and here we learned a switch is involved in ARP routing. This …
