US security agencies warn of threats to industrial, utility control networks

Key US government security organizations are warning that industrial control system (ICS)/supervisory control and data acquisition (SCADA)-based networks are being threatened by bad actors armed with custom software tools.The Department of Energy (DOE), Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA) and Federal Bureau of Investigation (FBI) issued a joint warning that certain advanced persistent threat (APT) actors have shown the ability to gain full system access to compromised ICS/SCADA systems.The alert did not identify which groups were making the threats, but it did recognize Dragos, Mandiant, Microsoft, Palo Alto Networks and Schneider Electric for helping put together the warning. Dragos has posted a paper about part of the threat.To read this article in full, please click here

MikroTik – RouterOS v7 – BGP performance testing for full tables

MikroTik has come a long way since the first release of RouterOS v7 beta.

One of the long-awaited features is improved BGP performance and the ability to leverage multiple CPU cores.

Testing BGP performance is a long process of lab and prod evaluation, so we decided to run some quick and basic tests to get a baseline.

When the CCR2216-1G-12XS-2XQ was released and MikroTik entered the world of 100G, we ordered some right away to test and just got them in the lab a few days ago – the results are below.

Hope this is helpful and look for more BGP perf tests in the coming months!

The BGP testing lab

TLDR; 2.1 million routes learned and forwarding in 46 seconds and withdrawn in 44 seconds. This was tested under a 25 Gbps load on both routers with a cpu load of 12%.

Lab overview: The lab consists of (2) CCR2216 routers running ROSv7.2 stable connected to a ProxMox hypervisor that runs (4) Linux route generators and MikroTik CHRs (also on 7.2) acting as border routers. The specific connectivity is in the overview drawing below.

IPv6: We are currently developing a route generator that will inject IPv4 Continue reading

What is DRaaS and how it can save your business from disaster

Disaster Recovery as a Service (DRaaS) provides data replication, hosting, and recovery services from the cloud in the event of a disaster, power outage, ransomware attack, or other business interruption.DRaaS backs up data, applications, and IT infrastructure to the cloud, with providers typically having geographically dispersed data center footprints. In the event of a disaster, the business will failover to the DRaaS provider’s data center in a different region. As opposed to traditional disaster recovery methods, which require businesses to operate an off-site DR facility, DRaaS shifts that burden to service providers, and, thus, expands the market beyond the large enterprises that could afford such capital-intensive setups.To read this article in full, please click here

Telephone System Is a Bad Example of Hierarchical Addresses

Networking engineers proposing strict hierarchical addressing scheme as a solution to global BGP table explosion often cite the international telephone system numbering plan (E.164) as a perfect example of an addressing plan that uses hierarchy to minimize routing table sizes. Even more, widespread mobile roaming and local number portability indicate that we could solve IP mobility and multihoming if only insert-your-favorite-opinion-here.

Nokia pulls most of its business from Russia

Finland-based telecommunications equipment giant Nokia has announced that it would cease most of its operations in Russia, in response to that country’s month-old invasion of Ukraine.Nokia said in a statement that it would suspend equipment deliveries, accept no new orders and move “our limited R&D activities” out of the country, saying that “it has been clear for Nokia since the early days of the invasion of Ukraine that continuing our presence in Russia would not be possible.”Russia accounted for less than 2% of the company’s net sales in 2021, according to Nokia, which added that the move will not affect the bottom line in a significant way, and that the company expects to hit all of its immediate earnings targets going forward.To read this article in full, please click here
