There are many aspects to security on Linux systems – from setting up accounts to ensuring that legitimate users have no more privilege than they need to do their jobs. This is look at some of the most essential security commands for day-to-day work on Linux systems.sudo
Running privileged commands with sudo – instead of switching user to root – is one essential good practice as it helps to ensure that you only use root privilege when needed and limits the impact of mistakes. Your access to the sudo command depends on settings in the /etc/sudoers and /etc/group files. [ Two-Minute Linux Tips: Learn how to master a host of Linux commands in these 2-minute video tutorials ]

Cryptocurrency such as Bitcoin has garnered most of the media coverage and hype to date, but keep your eye on blockchain – this new technology is poised to change IT in much the same way open-source software did a quarter century ago.
Industry bellwether Cisco revealed some important financial numbers this week – its revenues were $12.5 billion, up 4 percent for the third quarter year-over-year, with product revenue up 5 percent.But one of the of the more interesting tidbits is that the company said it was selling some 40 Catalyst 9000 systems a day in and has installed 2,700 of the big boxes this quarter bring the total to 5,800 since its introduction in 2017. The Catalyst 9000 is key to a number of Cisco’s future initiatives – one of the most important being its drive to build out its Network Intuitive plans for intent-based networking.[ Related: Getting grounded in intent-based networking] |

When it comes to security and manageability, Enterprise of Things (EoT) devices must have far more stringent requirements than consumer IoT devices, which often have virtually no built-in security. Indeed, enterprise use of consumer-grade IoT is highly risky.Making the matter even more urgent is the growing number of deployed EoT devices, which is expected to increase significantly over the next two to three years. (I estimate there will be more “things” in an enterprise than PC and mobile phone clients combined within three to four years.)To read this article in full, please click here
