The concept of “cyber security” refers to the methods, technologies, and processes used in protecting computer systems, networks, and data against cyber-attacks and unauthorized access. Cybersecurity aims to protect all organizational assets from internal and external threats as well as disruptions caused by natural disasters.
In general, it can be divided into the following pillars:
Software and services used within an organization are protected against a wide range of threats through application security. Developing secure application architectures, writing secure code, implementing strong data input validation, threat modeling, etc. are all required to minimize the likelihood of unauthorized access or modification.
A network security strategy involves implementing both hardware and software mechanisms to prevent unauthorized access, disruptions, and misuse of the network and its infrastructure. Multiple external and internal threats can be prevented by effective network security.
Mobile security refers to the protection of both organizational and personal information stored on mobile devices such as cell phones, laptops, and tablets from threats such as unauthorized access, device loss, and malware. Many businesses overlook the risks associated with mobile devices such as tablets and smartphones, which are often prone to malware, zero-day attacks, phishing, and IM (instant messaging) threats.
Security solutions offered by cloud providers are often inadequate to achieve enterprise-level security in the cloud. Cloud environments require supplementary third-party solutions to protect against data breaches and targeted attacks.
Often, threat actors exploit vulnerable devices inadvertently connected to the Internet for nefarious purposes, such as access to corporate networks or global bot networks. Discovering and classifying connected devices, controlling network activity via auto-segmentation, and protecting connected devices with IPS software are key elements of IoT security.
