Repost: L2 Is Bad

Roman Pomazanov documented his thoughts on the beauties of large layer-2 domains in a LinkedIn article and allowed me to repost it on ipSpace.net blog to ensure it doesn’t disappear

First of all: “L2 is a single failure domain”, a problem at one point can easily spread to the entire datacenter.

Cisco significantly bolsters security portfolio with $28B Splunk buy

Looking to significantly reinforce its security software portfolio, Cisco has struck a $28 billion cash deal to acquire enterprise and cloud protection company Splunk.Founded in 2003, Splunk’s software platform is known for its wide-reaching ability to search, monitor and analyze data from a variety of systems. Network security teams can use this information to gain better visibility into and gather insights about network traffic, firewalls, intrusion detection systems (IDSes), intrusion prevention systems (IPSes), and security information and event management (SIEM) systems, from on premise and or its cloud-based package, according to Splunk.To read this article in full, please click here

How network security can save security dollars

For the last twelve years, 100% of CIOs have said that they expect to spend more on IT security, making security the only category that just keeps on absorbing investment. Every year in the last three years, over 80% of enterprises have said that their IT security still needed improvement. So, like death and taxes, is security spending growth inevitable? If we keep on the way we have, it sure seems like it. But what might change?Let’s start with what’s important to users. External threats, meaning hacking, are a problem for every CIO. Internal threats, from badly behaving employees, are a problem for three out of four. Data theft is a universal fear, and malware that interferes with applications and operations is an important problem for over 90% of CIOs. As far as approaches or targets are concerned, 100% say access security on applications and data is essential and so is regular malware scanning. If you ask CIOs to pick a single thing they think is essential for IT security, it’s access security.To read this article in full, please click here

Both are designed to optimize network performance for employees and customers.The combination is ideal for SMBs with high data demands and growing traffic. The two new products work together to provide increased throughput and improved security with minimal effort, according to HPE Aruba Networking.To read this article in full, please click here

BGP Labs: Protect EBGP Sessions

I published another BGP labs exercise a few days ago. You can use it to practice EBGP session protection, including Generalized TTL Security Mechanism (GTSM) and TCP MD5 checksums1.

I would strongly recommend to run BGP labs with netlab, but if you like extra work, feel free to use any system you like including physical hardware.

  1. I would love to add TCP-AO to the mix, but it’s not yet supported by the Linux kernel, and so cannot be used in Cumulus Linux or FRR containers. ↩︎

New chip designs on display at Intel Innovation 2023

Intel took the wraps off a number of new chip designs during its Innovation 2023 event in San Jose, Calif. Among the highlights is a preview of fifth-generation Xeon processors, which gain performance improvements and faster memory while using the same amount of power as the current generation.Scheduled to launch beginning December 14 and going into 2024, the fifth generation of Xeon processors splits the structure into two different core designs: the P (for performance) core, codenamed Granite Rapids, and the E (for efficient) core, codenamed Sierra Forest. P cores are high-performance cores for maximum computing power, while E cores are smaller, much less power-hungry, and designed for simpler tasks.To read this article in full, please click here
