- 6 Steps to Securing Critical Infrastructure Operations Technology
- Securing hardware and software systems for power plants, water treatment facilities, transportation systems, and other critical infrastructure requires network visibility, vulnerability assessments, and overall strategic and incident response plans. As the nation increasingly relies on technology to power critical infrastructure and government operations, the need to secure operational technology becomes increasingly important. OT includes hardware and software systems used to control and monitor physical processes in power plants, water treatment facilities, transportation systems, and other critical infrastructure. These systems play a vital role in ensuring the safety and well-being of communities, and any disruption to their operation can have serious consequences. The challenge in securing OT is that these systems are developed for reliability and security, not security. Many OT systems are based on several

- An SRE who cannot build a data asset system is not a good maintenance person.
- 1. Understanding data assets 1. Data assets - the picture of enterprise IT value is shown in the figure. When data assetization is not implemented, data may be in a discrete state, data production and consumption are not unified, and data islands or zero benefits are prone to occur. . After building data capitalization, we integrate data from different channels and construct unified data sources or process links for data collection, storage, and analysis, and then unify the corresponding data structures, data relationships, and consumption outlets. After the operational data is collected and compiled, it can serve its own decision-making and business processes. 2. Data assets - taking operation and maintenance scenarios as an example. The picture above takes scenarios as an example to introduce the classification of data assets. To understand data assets, we must understand the three elements corresponding to data assets, namely data type, data form and data carrier.

- 2 ways to add users to SUDOERS group in Debian
- In DebianLinux, the SUDOERS group plays a vital role in granting administrative rights to users. Adding users to the SUDOERS group enables them to execute commands with root privileges, thereby providing them with the necessary administrative access to perform various tasks on Debian systems. During the installation of Debian Linux, if you leave the password for the root account blank, the first user created on the system will have administrative rights. However, if you set a root password, the username will not have sudo permissions. Therefore, you may encounter errors similar to the following while using the user account to perform administrative tasks. isnotinthesudoers

- After interviewing some operations and maintenance, I found 3 common points
- Recently, due to some reasons, I needed to recruit an operation and maintenance personnel, so I screened a lot of resumes and interviewed many people. I found that everyone had the same problems. Mainly in the following aspects: The focus of the resume is unclear, but the personal plan is not clear. Let me talk about my views from these three aspects. The focus of the resume is not clear. The resume is very important. The resume is very important. The resume is very important. A resume is a stepping stone for a person. Whether you can get an interview depends on whether your resume meets the needs. I have never met you, and I know very little about you. How can I understand you? Just your resume. However, I don’t know if it’s a common problem in IT jobs or if it’s unique to those in operation and maintenance jobs. I found that most people’s resumes are just like those in charge of virtualization.

- An article on how to optimize the performance of LLM using local knowledge base
- Yesterday, a 220-hour fine-tuning training was completed. The main task was to fine-tune a dialogue model on CHATGLM-6B that can more accurately diagnose database error information. However, the final result of this training that I waited for nearly ten days was disappointing. Compared with the training I did before with a smaller sample coverage, the difference was quite big. This result is still a bit disappointing. This model basically has no practical value. It seems that the parameters and training set need to be readjusted and the training is performed again. The training of large language models is an arms race, and it is impossible to play without good equipment. It seems that we must also upgrade the laboratory equipment, otherwise there will be few ten days to waste. Judging from the recent failed fine-tuning training
