SECURITY ARCHITECTURE AND DESIGN Security architecture is the strategic design of systems, policies and technologies to protect IT and business assets from cyberthreats. A well-designed security architecture aligns cybersecurity with the unique business goals and risk management profile of the organization.

But for organizations to come out ahead, they must shift their risk management approach from reactive to proactive. That means building in security from the beginning instead of fixing breaches only when they occur.

It also helps determine when and which technologies to implement, giving security decision-makers the ability to add new capabilities as the threat landscape evolves.

Organizations are under constant threat of attack, including denial of service, data theft, ransomware and extortion. 2. Attackers are more sophisticated through the use of automation, machine learning and artificial intelligence (AI). 3. Attackers have access to larger sources of funding, sometimes through government sponsors or organized crime. They also have access to tools such as ransomware as a service (RaaS). 4. A distributed workforce increases the risk of internal breaches caused by malicious insiders and/or negligence or ignorance by employees.

They then build a framework to mitigate the potential damage cyberthreats can inflict.

At the same time, security embedded into an organization’s DNA (such as Zero Trust) ensures that security is a vital part of every development cycle. This eliminates gaps and enables a risk-free environment for DevOps to build and innovate.

That’s why many of today’s breaches are the result of breakdowns in security processes. A strong security architecture closes those gaps and provides protocols in the event of a breach. Security teams are equipped to respond immediately and eliminate threats — oftentimes with cybersecurity automation — before they become a larger problem.

But the increasing complexity of IT infrastructure can often cause gaps in risk posture — on top of costing time, money and talent to manage the architecture. An efficient security architecture — such as those built on cybersecurity consolidation — is designed with fewer products and vendors. Tools are integrated, where critical updates, threat response and user experiences are all closely managed. This creates a highly scalable cyber infrastructure that maximizes operational efficiency.

For example, healthcare providers in the US must comply with HIPAA regulations, while businesses in the EU must meet GDPR requirements. Creating a strong security architecture and incorporating security into every part of the organization not only helps prevent cyberattacks but also ensures compliance with relevant authorities and regulations.

Solicit input from key stakeholders, including the executive suite, lines of business, DevOps, IT and more. Have the CISO and cyber team spearhead the effort.

This may include cybersecurity consolidation; increased use of automation, AI and machine learning; Zero Trust; compliance; endpoint protection; and preventing known and unknown zero-day threats in real time.

Continue collaboration and information sharing on an ongoing basis.
