What is Zero Trust Security, and why is it Important for Continuous Delivery?

Enterprise Security Magazine | Thursday, March 24, 2022

The Zero Trust concept believes that an organization's network security is constantly vulnerable to external and internal threats.

FREMONT, CA: Zero Trust is a security approach that enables the DevSecOps team to address vulnerabilities resulting from significant digital transitions, such as cloud adoption, decentralized infrastructure, and container technologies. Although they have allowed teams to provide products and services efficiently, the traditional security methods pose a grave hazard. Trusting anyone within the organization's network was fundamentally flawed and required revision.

A Zero Trust ecosystem is challenging to accomplish from a technological and cultural standpoint, but its ramifications can be far-reaching if implemented correctly. The process will also be time-consuming and resource-intensive. DevSecOps must incorporate this security factor throughout software development, not as an afterthought.

Security perimeters are outmoded: Historically, IT departments assumed that anything within their network was secure. Unfortunately, this is no longer the case. Security is now more crucial than ever before. Inadequate perimeter-based security techniques that were effective in the container environment are now a recipe for disaster. The internal vulnerability of systems designed to repel external attacks has increased. Advanced trojan files and malicious software can quickly overcome perimeter-based defenses and ruin the entire IT infrastructure.

Cloud is less secure: Today, enterprises have distributed multi-cloud apps and services accessible on any device and from anywhere in the world. When a business deploys its application to a public cloud, such as Google, Amazon, or Microsoft Azure, the data travels/spreads beyond the security of its on-premises servers.

Solar winds mega-breach and Colonial Pipeline's DarkSide Intrusion are two significant security incidents in which malware attacks affected a whole infrastructure.

The importance of implementing security best practices is equivalent to that of coding: Microservices and distributed architecture provide agility and scalability but also impose additional duties on developers and engineers. In addition to designing business logic and scripts, they must now deal with security and networks.

Remote is the new standard: Most modern IT businesses have embraced remote-first or hybrid work arrangements, resulting in a globally dispersed workforce. Consequently, many consumers and staff contact the IT network via unmanaged IPs and devices. This makes it challenging for IT staff to maintain network security in the face of more sophisticated attackers. In addition, employees' home networks offer an increased risk to the firm.

Patchwork introduces weaknesses: Patchwork security methods make organizations more vulnerable to threats; therefore, their security teams are more likely to spend more time maintaining these devices.

Insufficient Security-first initiatives: The rising prevalence of Software Delivery Orchestration solutions has enabled teams to accelerate deployments. Now, businesses may deploy applications to production on demand. Nevertheless, organizations continue to lag in adopting a security mindset with a systematic approach and infrastructure.

Businesses are increasingly transitioning to the cloud and integrating more systems and users into distributed work environments. Cybersecurity has become a core operational issue for companies across the APAC region. A cyber security consultancy solution assists companies to determine the level of security they have in place, pinpoint vulnerabilities and establish controls that are appropriate to their technology environment. Vulnerability identification is not the only part of effective consulting. It links security architecture, governance, employee practices and incident preparedness to ensure security measures don't burden business activities with undue complexity. Shifting Cybersecurity Priorities across APAC Digital infrastructure is becoming more interconnected, leading organizations in the APAC region to prioritize security architecture. Cloud platforms, remote access, application programming interfaces and connected devices can provide other ways into business systems. Consultants in cybersecurity are also being asked to look at how systems interact, which goes beyond simply evaluating technologies. Secure boundaries are offered by network segmentation, identity controls and secure configuration, while maintaining business activity. Identity management is becoming increasingly important as organizations grant employees, contractors, and partners access to digital resources from various locations. Using a password alone might not be enough to ensure control for some sensitive systems. Having strong authentication, role-based access, and privileged account management can eliminate unnecessary exposure. Access requirements to business roles can be mapped, and the unnecessary access permissions will be eliminated without interfering with business processes. Regulatory expectations also have an impact on cybersecurity strategies in APAC. Local laws may have different regulations pertaining to privacy, data handling, reporting, and security controls. There are situations where organizations have a need to have a uniform security strategy across countries, but also meet local requirements. A structured compliance assessment can match regulatory requirements to current policies and controls and point to where policies or technical controls could be modified. Another key factor is third-party risk, as businesses rely increasingly on vendors for software, cloud services and operational support. Even with good internal controls, a security problem can exist in a supplier's system that could impact connected business systems. It is possible to gain more visibility of external exposure through vendor assessments, contractual security requirements and ongoing monitoring. Support can be consulted to develop realistic risk levels to ensure that critical suppliers are investigated in more detail than less significant suppliers. Strengthening Security through Practical Solutions Balancing the use of legacy systems and newer digital platforms can make cybersecurity evaluations challenging. One approach that can be used is to develop an inventory of the assets, identify key systems and flows, and map out key systems and flows and their interdependencies prior to recommending controls. Then, consultants can prioritize the security improvements based on the business impact and exposure. This way, the same controls are not applied to systems having vastly different risk profiles. Incident response will require coordination between technical and business teams. Security tools could be available in an organization, but there is no clear set of responsibilities for incident response. Incident response planning allows for the creation of escalation procedures, decision-making authority, procedures for evidence handling, and communication procedures prior to an incident. Tabletop exercises allow for testing of the plan and identifying gaps without having to wait for a security incident to occur. Access issues are created in remote and hybrid work settings. The devices can be on various networks and locations, making endpoint security and identity controls more critical. Assessing users, devices and access requests can provide some help with zero-trust principles, where network location is not enough to grant them trust. Combining endpoint management, multi-factor authentication and conditional access can increase security and flexibility in the workplace. Advancing Cybersecurity Capabilities and Stakeholder Value The use of AI and sophisticated analytics is growing the capabilities of cybersecurity in APAC. An analytical system can process huge amounts of data on network and endpoint activities to check if the patterns are abnormal when compared to the norm. Organizations can use consultants to decide where automated analysis is valuable and still requires human interaction. A well-managed automation can enhance detection time without the paradigm of letting uncalled-for decisions dictate critical security activities. Security orchestration is also enhancing the organization's response to recurring threats. Automated workflows can isolate the affected endpoints and deactivate compromised accounts or trigger predefined investigation steps if certain conditions are detected. Well-developed playbooks can minimize response times while maintaining the proper review of necessary responses. Automation can be especially beneficial in handling repetitive work tasks that were previously taking up valuable staff time in the security team. Continuous security validation is another chance to improve security programs. Organizations can periodically test access controls and detection capabilities, as well as configurations, on a regular basis. Security testing and attacks can be simulated to determine if protection is effective. Results can then be directly applied to remediation and security enhancement programs. ...Read more
