Servers are a major focus of cyberattacks, and when setting up a security infrastructure, putting applications to work on Server Security should be your first concern. However, getting your applications to work properly without meeting the security needs of your infrastructure can have devastating consequences in the future.
Today we separate some tips where we will talk about some basic security practices that are best configured before or while you configure your applications.
SSH keys are SSH authentication keys to enhance remote server security. If you run a server and it runs constantly online, you probably have access to it via SSH (Secure Shell). SSH Keys work in public key and private key mode (always in pairs), where the SFTP / SSH connection is only allowed if the client computer user’s private key matches the server user’s public key.
A firewall is a piece of software or hardware that controls which services are exposed to the network. This means blocking or restricting access to all ports except those that should be publicly available.
VPNs and Private Networks:
Private networks are networks that are available only to certain servers or users. A VPN, or Virtual Private Network, is a way of creating secure connections between remote computers and presenting the connection as if it were a local private network.
SSL / TLS:
Wildcard SSL Certificate or TLS certificates can be used to authenticate different entities with each other. After authentication, they can also be used to encrypt the communication.
Up to this point, we have discussed some technologies you can implement to improve your security. However, a large part of security lies in analyzing your systems, understanding available attack surfaces, and blocking components as best you can.
File Auditing and Intrusion Detection Systems:
File auditing is the process of comparing the current system against a record of the files and the file characteristics of your system when it is in a good and known state. This is used to detect system changes that may have been authorized.
Isolated execution environments:
Isolated execution environments refer to any method in which individual components are executed within their own dedicated space.
The strategies described above are just some of the enhancements you can make to improve the security of your systems. It is important to recognize that while it is better late than never, security measures diminish in effectiveness as you take longer to implement them. Security cannot be an afterthought and should be implemented early on along with the services and applications you are providing.
The increasing adoption of new technologies and increasing data breaches, which today cost businesses an average of $ 3.86 million a year, have created a vast field for information security analysts.
For example in the United Kingdom, the annual salary of a professional in the field is about 164 thousand reais, and the value should grow in the coming years.
What does an information security analyst do?
Information security analysts like Ddos protection service protect business data by analyzing their IT environment to identify vulnerabilities and recommend best practices for data protection and threat mitigation. It is noteworthy that not every job advertisement will have the title of “information security analyst”. Similar positions include names such as security analyst, information security consultant and cybersecurity analyst.
Which people are suitable for information security analyst positions?
Professionals must have an analytical mindset, with an emphasis on cybersecurity and knowledge of the latest technologies. They are often people who have a technical personality with IT skills, but they also need to be good communicators to ensure that company employees understand the security risks for the organization.
What are the main job descriptions?
- Be responsible for analyzing corporate risks related to information managed by IT systems and infrastructure.
- Protect company information by defining confidentiality, integrity, and availability criteria.
- Perform testing by detecting threats and vulnerabilities in IT services that compromise corporate information.
- Conduct analysis and control of processes to identify if they are appropriate to the security measures and policies adopted.
- Monitor and report information security metrics.
- Define procedures and policies, as well as maintain up-to-date information security documentation, services, and technical procedures.
- Perform periodic analysis of activity records of access control systems (logical/physical)
- Identify and investigate anomalous security situations
- Participate in the management of vulnerabilities and monitoring the resolution of detected nonconformity situations
- Investigate and report security incidents
- Perform other activities at management’s discretion and more.
Which certifications are best for information security analysts?
Abroad, some of the top certifications for information security analysts are: SSCP (Certified Security Certified Practitioner), Certified Cyber Professional (CCP), Certified Information System Security Professional (CISSP), Certified Ethical Hacker (CEH) and GCHQ Certified Training (GCT).
The scarcity of cybersecurity manpower means good growth prospects for information security analysts. Professionals often begin their careers in secondary security roles and then have room to progress to information security manager and information security consultant positions.
