1. Cyber Security
Cyber security is the defense of computers, servers, mobile devices, electronic systems, networks and data against harmful attacks. It is also known as IT security or the security of electronic data what is connect to the internet. The term is broad and applies to everything that has to do with computer security, disaster recovery and familiarising end users.
2. IT Security
IT Security is the defense Personal, ID, Data Protection, Identity Protection. etc. Also know making anonymous, pseudonymised and protect it with encryption and security of housing, personality and saving backend end security protection.
3. Data Encryption
Encrypting internal data is important when there are multiple trust zones in the data centre. The most common trust zones can come about from having multiple companies sharing a data centre. Having a network encryption ensures that in the event that packets going to one machine ends up arriving at the wrong one, they'll be in a form that's unreadable to tenants from different trust zones.
However even if a single company owns the entire data centre, usually a large companies are composed of multiple departments and it's often necessary for a security conscious company to enforce internal boundaries. For example, Accounting systems may be segregated from HR systems except through a number of predefined exchange points that can be monitored.
Another common reason why you want internal encryption is to protect from physical attacks, from interception of cables between machines. In a large data centre, you will have cables going from many different directions. You may not want the cleaning service staffs to have access to the locked server racks, but you may have cables that need to cross racks. When a data centre gets sufficiently complicated, it can be difficult to keep track of which cable needs to go where and which needs to be encrypted, so having a global must-encrypt policy can actually reduce the load on decision making process. In another scenario, you may want to enforce a two man rule where nobody can have physical access to a machine alone. Encrypting the local traffic can reduce the amount of zones that would be considered a two-man zones.
An IT security audit is needed to ensure that your cyber-defences are as up to date as they can be, in order to effectively respond to the threats posed by hackers and other such criminals who manipulate IT systems for their own ends. Should an IT system’s defences be found wanting when compared to the cutting-edge approaches used by hackers, then everything your business has worked for could be at risk. Just a single vulnerability can lead to not only your bank details and subsequently your cash being stolen, but also your personal data that you wouldn’t want being made public knowledge. Businesses in particular are a tempting target for cyber-criminals, as the thinking is that whilst they have significant cash reserves due to being a commercial entity, they are unlikely to have a seizable team or level of resources solely dedicated to IT protection. Due to their attention being diverted elsewhere, an infiltrator can go about their business without being detected, whereas a larger company with greater manpower would be able to quickly detect that something is amiss.
System/Security event logging and monitoring are two parts of a singular process that is integral to the maintenance of a secure infrastructure. Every activity on your environment, from emails to logins to firewall updates, Bios until identity system and scripts deployments, is considered a security event. All of these events are, (or should be,) logged in order to keep tabs on everything that’s happening in your technology landscape. When it comes to monitoring those logs, organizations will examine the electronic audit log files of confidential information for signs of unauthorized activities.If unauthorized activities (or attempts thereof) are found, the data will be moved to a central database for additional investigations and necessary action. In a time where digital threats are widespread and ever-changing, the data gleaned from these log files is vital in keeping the infrastructure agile and responsive.
Systems hardening is a collection of tools, techniques, applications and best practices to reduce vulnerability in technology applications, systems, infrastructure, firmware, and other areas. The goal of systems hardening is to reduce security risk by eliminating potential attack vectors and condensing the system’s attack surface. By removing superfluous programs, accounts functions, applications, ports, permissions, access, etc. attackers and malware have fewer opportunities to gain a foothold within your IT ecosystem. Systems hardening demands a methodical approach to audit, identify, close, and control potential security vulnerabilities throughout your organization. There are several types of system hardening activities, including: Application hardening, Operating system hardening, System/Server hardening, Database hardening, Network hardening and Embedded hardening. Although the principles of system hardening are universal, specific tools and techniques do vary depending on the type of hardening you are carrying out. System hardening is needed throughout the lifecycle of technology, from initial installation, through configuration, maintenance, and support, to end-of-life decommissioning. Systems hardening is also a requirement of mandates such as PCI DSS and HIPAA etc.
7. Identity Management
Identity and access management (IAM) in enterprise IT is about defining and managing the roles and access privileges of individual network users and the circumstances in which users are granted (or denied) those privileges. Those users might be customers (customer identity management) or employees (employee identity management. The core objective of IAM systems is one digital identity per individual. Once that digital identity has been established, it must be maintained, modified and monitored throughout each user’s “access lifecycle.” Systems like FreeIPA, OpenLDAP, Active Directory and Radius with API are in our portfolio.
8. Red and Blue Teams
Red teams are focused on penetration testing of different systems and their levels of security programs. They are there to detect, prevent and eliminate vulnerabilities. A red team imitates real-world attacks that can hit a company or an organization, and they perform all the necessary steps that attackers would use. By assuming the role of an attacker, they show organizations what could be backdoors or exploitable vulnerabilities that pose a threat to their cybersecurity. A common practice is to hire someone outside the organization for red teaming someone equipped with the knowledge to exploit security vulnerabilities, but unaware of the defenses built into the organization’s infrastructure. The techniques a red team uses vary from standard phishing attempts aimed at employees and social engineering to impersonating employees with the goal of obtaining admin access. To be truly effective, red teams need to know all the tactics, techniques and procedures an attacker would use. Red teams offer critical benefits, including a better understanding of possible data exploitation and the prevention of future breaches. By simulating cyber attacks and network security threats, companies make sure their security is up to par with the proper defenses in place.
A blue team is similar to a red team in that it also assesses network security and identifies any possible vulnerabilities. But what makes a blue team different is that once a red team imitates an attacker and attacks with characteristic tactics and techniques, a blue team is there to find ways to defend, change and re-group defense mechanisms to make incident response much stronger.Like a red team, a blue team needs to be aware of the same malicious tactics, techniques and procedures in order to build response strategies around them. And blue team activity isn’t exclusive to attacks. They’re continuously involved to strengthen the entire digital security infrastructure, using software like an IDS (intrusion detection system) that provides them with an ongoing analysis of unusual and suspicious activity. Some of the steps a blue team incorporates are: Security audits, such as a DNS audit, Log and memory analysis, pcap, Risk intelligence data analysis, Digital footprint analysis, Reverse engineering, DDoS testing and Developing risk scenarios.
