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.

What is IT security?

IT security protects the integrity of information technologies such as 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 are secured by 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.

Why is IT security important for business?

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.

What is container security?

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.

What is cloud security?

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.

What is hybrid cloud security?

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.

What is API security?

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.

The US government spends $ 13 billion annually on cybersecurity, but reports that cyber attacks continue to evolve at a breakneck pace. To fight the proliferation of malicious code and facilitate its early detection, the National Institute of Standards and Technology (NIST) recommends continuous and real-time monitoring of all electronic resources.
