Infrastructure security encompasses not just defense against classic cyberattacks, but also protection over natural catastrophes and other calamities. It also touches on the subject of resilience, which is concerned with how an organization recovers after an attack or other interruption. The ultimate aim is to improve security and reduce downtime, as well as the accompanying customer attrition, brand and reputation damage, and compliance expenses that firms incur.
It is a high-level method of thinking about the protection of an organization’s whole technological perimeter.
Although there is no general definition of the various levels or categories of infrastructure security, one frequent approach in the company is to secure the following four levels:
Infrastructure requires physical protection such as closed doors, fences, backup generators, and security cameras. A physical security strategy should also include failover strategies that find backup equipment in another area of the world.
Network security safeguards data as it moves into, out of, and across a network. This includes on-premises and cloud traffic encryption, correct firewall management, and the usage of identity and authorisation systems.
At the application level, security must also be considered. This covers database security against SQL injection attacks, as well as hardening other programs against unauthorized access or harmful exploits.
Data protection must be considered at the lowest level of infrastructure security, regardless of where or how it is kept. When applicable, this includes data encryption, backups, and anonymization techniques.
Infrastructure security, is essential for preventing harm to technological assets and data as a result of an attack or disaster. It’s also vital for limiting the amount of damage caused by a successful attack or a natural disaster. Similarly, the fundamental purpose of infrastructure security is to reduce the organization’s total risk level, which reduces the likelihood of a severe operational interruption and/or financial damage.
The IT architecture of today’s business is significantly more complicated than it has ever been, with on-premises and cloud-based systems, company-owned and employee-owned devices (including laptops and smartphones), and even Internet of Things (IoT) devices like cameras and industrial sensors. Many of these devices were either not designed with security in mind or had a patchwork of security solutions done after the fact. Finally, the management organization is responsible for securing all of these systems.
Infrastructure security is the lynchpin of every company’s overall security strategy since it sits at the heart of their technology operations. It may be thought of as the organization’s master security strategy, which underpins tactical strategies and everything else that is produced around it.
The major technologies used to defend infrastructure are cybersecurity, or IT security, solutions. It’s not a matter of whether or whether cybersecurity solutions can secure your infrastructure; rather, it’s a question of how to best defend your infrastructure with them.
Cybersecurity solutions can be used to ensure that only authorized users have access, prevent malware from being installed on infrastructure devices, assess the network’s overall security (including penetration testing to simulate an attack), and encrypt data in transit and at rest to protect it in the event of a successful attack.
All of these methods, when combined, form the foundation of a solid infrastructure protection program.
