Understanding IT security

Copy URL

IT security is an umbrella term that includes network, internet, endpoint, API, cloud, application, container security, and more. It's about establishing a set of security strategies that work together to help protect your digital data. Not so long ago IT security was a checkpoint at the end of a development cycle. It was slow. Businesses today are looking for ways to create an integrated security program so that they can adapt faster and more efficiently. Think of it as security that is built in, rather than bolted on.

Security checklist

Top security and compliance considerations for IT modernization

IT security protects the integrity of information technologies like computer systems, networks, and data from attack, damage, or unauthorized access. A business trying to compete in a world of digital transformation needs to understand how to adopt security solutions that begin with design. This is what it means to "shift security left"—to make security a part of the infrastructure and product lifecycle as early as possible. This helps security be both proactive and reactive.

Continuous security is fed by a routine system of feedback and adaptation, often handled through the use of automatic checkpoints. Automation ensures fast and effective feedback that doesn’t slow the product lifecycle down. Integrating security in this way also means that updates and responses can be implemented quickly and holistically as the security landscape changes.

IT security continues to be a top funding priority for companies. This checklist details key security-related features for your modernization strategy to help you free up resources and reduce security and compliance risk.

Traditionally IT security was focused on fortifying, maintaining, and policing the datacenter perimeter—but today that perimeter is dissolving. The way we develop, deploy, integrate, and manage IT is dramatically changing. Public and hybrid clouds are redistributing responsibility for regulatory compliance and security across multiple vendors. The adoption of containers at scale requires new methods of analyzing, securing, and updating the delivery of applications. Mobile apps are spread across a multitude of devices, and more and more infrastructure is moving from hardware to software. The traditional ways of managing security aren’t keeping up. Digital transformation demands a change in security programs—security must be continuous, integrated, and flexible in a digital world.

For some businesses, doing security right means hiring a Business Information Security Officer. BISOs are embedded in the business and involved in the product lifecycle from design to delivery and adoption. They report to the Chief Information Security Officer (CISO) to make sure that security concerns are thoughtfully managed and integrated at every stage, balancing security needs with risk to the business to ensure fast delivery that functions as it should.

Security-Enhanced Linux (SELinux) is a security architecture for Linux® systems that allows administrators to have more control over who can access the system. It was originally developed by the United States National Security Agency (NSA) as a series of patches to the Linux kernel using Linux Security Modules (LSM).

SELinux was released to the open source community in 2000, and was integrated into the upstream Linux kernel in 2003.

Containers make it easy to build, package, and promote an application or service across different environments and deployment targets. But there are some challenges to container security.

Static security policies and checklists don’t scale for containers in the enterprise. The supply chain needs more security policy services. Teams need to balance the networking and governance needs of containers. Build and runtime tools and services need decoupling.

Zero Trust is an approach to designing security architectures based on the premise that every interaction begins in an untrusted state. This contrasts with traditional architectures which may determine trustworthiness based on whether communication starts inside a firewall. More specifically, Zero Trust attempts to close gaps in security architectures that rely on implicit trust models and one-time authentication.

Zero Trust has gained popularity because the global threat landscape has evolved, challenging long held assumptions about the inherent trustworthiness of activities inside a network. Well-organized cybercriminals can recruit insiders, and continue to find new ways past the outer shell of traditional security architectures. Sophisticated hacking tools and commercialized ransomware-as-a-service platforms have also become more widely available, making it easier for new kinds of financially-motivated criminals and cyber terrorists to operate. All of these threats have the potential to exfiltrate valuable data, disrupt business and commerce, and impact human life.

While many people understand the benefits of cloud computing, they’re equally deterred by the security threats. We get it. It’s hard to wrap your head around something that exists somewhere between amorphous resources sent through the internet and a physical server. It’s a dynamic environment where things are always changing—like security threats.

Hybrid cloud environments offer users a lot of choice and flexibility. You can keep sensitive or critical data off of the public cloud while still taking advantage of the cloud for data that doesn’t have the same kinds of risk associated with it. Here are some of the challenges of hybrid cloud security, and the tools you need to solve them.

You probably don’t keep your savings under your mattress. Most people keep their money in a trusted environment (the bank) and use separate methods to authorize and authenticate payments. API security is similar. You need a trusted environment with policies for authentication and authorization.

API security best practices include the use of tokens, encryption and signatures, quotas and throttling, and an API gateway. Most importantly, though, API security relies on good API management.

Malware, short for malicious software, is any software that acts against the interest of the user. From ransomware to adware to botnets, malware is responsible for destroying data, violating people's privacy, and causing countless hours of lost productivity. Malware can affect not only the infected computer or device but potentially any other device the infected device can communicate with. Malware attacks are a severe threat, but effective IT security can reduce your organization’s exposure.

CVE, short for Common Vulnerabilities and Exposures, is a list of publicly disclosed computer security flaws. CVE is also shorthand for the CVE ID number assigned to a security flaw. CVEs help IT professionals coordinate their efforts to prioritize and address these vulnerabilities to make computer systems more secure.

Containers and hybrid cloud technologies have made the security landscape much more complex. Security teams are increasingly finding it challenging to keep up with the changing risks, compliance requirements, tools, and architectural changes introduced by these technologies. Traditional perimeter-based network security is no longer effective on its own, and security teams must rethink their approach.

Red Hat takes a layered, defense-in-depth approach that helps customers implement security across the entire infrastructure and application stack and life cycle.

Want to report a vulnerability? Need help now?

Connecting with a community and solving problems together is the future of security.

We want you to have confidence as you adopt a continuous security strategy. We do that by making open source ready for the enterprise. Every year, we release the Red Hat product security risk report, which details our support team's response to the known security vulnerabilities affecting enterprise software around the world that year.
