Your decommissioned routers could be a security disaster

Here's bad news: It's easy to buy used enterprise routers that haven’t been decommissioned properly and that still contain data about the organizations they were once connected to, including IPsec credentials, application lists, and cryptographic keys.“This leaves critical and sensitive configuration data from the original owner or operatoraccessible to the purchaser and open to abuse,” according to a white paper by Cameron Camp, security researcher, and Tony Anscombe, chief security evangelist, for security firm Eset (See: Discarded, not destroyed: Old routers reveal corporate secrets).To read this article in full, please click here

Who is selling NaaS, and what do you get?

Vendors of all stripes—network hardware vendors, telcos, hyperscalers, and a new generation of cloud-based upstarts—are jumping on the network-as-a-service (NaaS) bandwagon, so it can be confusing to sort out who is offering what.Even the definition of NaaS is somewhat fluid. Is NaaS simply procuring networking gear on a pay-as-you go, subscription basis rather than buying it? Is NaaS just a different way of describing a managed service?Or is NaaS something fundamentally different that addresses a growing challenge for network execs: how to provide network connectivity, resiliency, security, and scalability in a multicloud world?To read this article in full, please click here

Colocation vs. cloud: SEO firm finds cloud to be cost prohibitive for its high density computing

A software firm in Singapore claims it would cost more than $400 million over three years if it were to migrate from its existing colocation setup and move its workloads to the Amazon Web Services (AWS) cloud. Notably, the firm runs a very compute-intensive environment, and high density computing can be very expensive to duplicate in cloud environments.Ahrefs, which develops search engine optimization tools, made the $400 million claim in a March 9 blog post by one of the company’s data center operations executives, Efim Mirochnik. Mirochnik compared the cost of acquiring and running its 850 Dell servers in a colocation provider’s data center with the cost of running a similar configuration in AWS.To read this article in full, please click here

Recording your commands on the Linux command line

Recording the commands that you run on the Linux command line can be useful for two important reasons. For one, the recorded commands provide a way to review your command line activity, which is extremely helpful if something didn't work as expected and you need to take a closer look. In addition, capturing commands can make it easy to repeat the commands or to turn them into scripts or aliases for long-term reuse. This post examines two ways that you can easily record and reuse commands.Using history to record Linux commands The history command makes it extremely easy to record commands that you enter on the command line because it happens automatically. The only thing you might want to check is the setting that determines how many commands are retained and, therefore, how long they're going to stay around for viewing and reusing. The command below will display your command history buffer size. If it's 1,000 like that shown, it will retain the last 1,000 commands that you entered.To read this article in full, please click here
