IT security refers to the protection of a computer system against malicious actors. When a malicious actor accesses a computer system, they can gain access to information that can be used for illicit purposes. This could result in unauthorized access to a company’s data, products, customers, and employees. Information technology security is also known as cyber security.
Application and API security
Application and API security are critical for organizations to protect themselves against cyberattacks. Attackers can exploit applications and API vulnerabilities to gain data access or compromise networks. The failure to address application and API security can result in significant damage.
Security threats range from bots and malware to denial of service (DoS) attacks. APIs are a popular target for hackers looking to break into systems and steal data. The most common attack vectors are OS Command Injection and SQL Injection.
As the number of hackers using web applications increases, businesses must be prepare to implement strong security measures to protect their organizations from these attackers. Fortunately, there are a variety of tools available that can be use to evaluate and protect APIs.
Network intrusion detection system (NIDS)
A network intrusion detection system is an IT security tool that monitors the traffic on your network and detects any suspicious activity. Its primary purpose is to see and stop any threats before they cause damage. To do this, it must be configured correctly, and the device needs to be kept up to date.
Network intrusion detection systems come in many different forms. Some are simple to set up, while others require a lot of configuration. There are also several free, open-source solutions available.
NIDS works by analyzing packet headers. These include information such as the source and destination IP addresses, protocol types, and ports. They then compare these to a database of known attack signatures. The system generates an alert when an instance matches the signature.
Next-generation antivirus (NGAV)
Next-generation antivirus (NGAV) is an integral part of a comprehensive IT security program. It helps companies to block attacks faster, minimizes post-breach costs, and lessens disaster risks. NGAV relies on a combination of techniques to detect and prevent unknown and known threats.
Unlike traditional antivirus, NGAV uses a combination of artificial intelligence and machine learning to identify suspicious behaviors. These methods can process endpoint activity in near real time. This gives the system the ability to identify and stop rapidly evolving threats.
Next-generation antivirus can also be cloud-based. This mode can be deployed on many endpoints without signature updates or on-premises management infrastructure.
NGAV products integrate with current SIEMs and third-party intelligence to help companies analyze endpoint activities and determine what’s causing an attack. The results are actionable information that can be used to protect against the most sophisticated cyber threats.
Incident response (IR)
Incident response (IR) is a strategy that helps organizations recover from a cyberattack. The goal is to limit the damage to IT infrastructure, reduce recovery time, and protect the organization’s reputation.
IR is a process that requires coordination among all parties involved in the incident. This includes IT staff, business leaders, and legal representatives. It should consist of clear escalation paths, standard operating procedures, and communication plans. A well-developed plan can help ensure the smooth running of the incident response process.
IR involves identifying a potential threat, examining evidence, and developing a response. Often, an IR plan is not set before an incident occurs. However, it can be a vital tool to guide an organization during a crisis.
An effective incident response process includes a documented procedure that aligns with the organization’s risk tolerance. It also contains lessons learned and performance metrics.
Physical security is a significant part of your organization’s overall security plan. An excellent physical security strategy will protect your employees and assets from internal and external threats.
The best physical security strategies will use technology and human interaction to keep your business safe. This may include cameras, CCTV, and even guards.
Another component of a physical security strategy is access control. Access control ensures that only authorized personnel have access to certain areas. Keeping track of how many people have entered or exited a particular area can help determine whether or not a secure site has been breached.
Other physical security components include lights, sensors, and temperature controls. These are all necessary to keep a building secure.
