KULLANIM ÖRNEKLERİNE GÖRE
In our application-driven economy, many organizations have turned to web applications and application programming interfaces (APIs) to power a wide range of business processes. From streamlining customer communication and employee collaboration to securely storing data, these tools have become vital components of modern business workflows. For this reason, apps and APIs have also become primary targets for motivated cyber criminals.
Because apps and APIs contain more valuable information than ever before, bad actors are attempting to exploit their vulnerabilities—such as application design flaws or weaknesses in APIs, open-source code, or access management security—at any chance they can get. Worse, attack vectors against apps and APIs are expanding, especially as application architectures become more complex and apps are deployed across multiple IT environments.
Organizations with remote or hybrid workforces have introduced even more app and API security risks as well, as the networks and devices that employees use to access their company’s apps may not be properly secured. This, combined with the ever-evolving sophistication of cybercriminals and their attack techniques, makes properly securing your apps and APIs a challenge.
Protecting your organization’s applications and APIs is critical to avoid things like reputation damage, financial loss, or legal exposure in the event of a successful cyberattack. To ensure your organization's apps and APIs are protected regardless of their complexity, where they are deployed, or what networks or devices your employees are using to access them, robust application security is essential.
Application security is the practice of deploying security tools, processes, and best practices throughout the entire application lifecycle to safeguard enterprise applications and APIs from internal or external attacks, privilege abuse, or data theft. As apps and APIs contain valuable data, cyber criminals are more motivated than ever to source and exploit their vulnerabilities to steal sensitive information or intellectual property.
Enterprise applications are critical components of our modern-day businesses, as they work to integrate core business programs and processes into a single software architecture to enhance efficiency, productivity, and communication across your entire organization. This means that your applications inherently provide gateways to valuable corporate data and sensitive information, and that makes them a primary target for sophisticated cyber-attacks. Protecting your enterprise applications with the proper security measures is key to safeguarding your business.
The application threat landscape is vast, which means your organization must mitigate security risks throughout the entire application lifecycle. The Open Web Application Security Project® (OWASP), in its bid to help businesses reduce their security exposure, has compiled a list of the top 10 critical security risks for applications your organization should be prepared for, including the following types of attacks:
Today, many types of multi-vector attacks seek to take advantage of security risks flagged by OWASP to target applications and application programming interfaces (APIs). Some of the most common include:
Application layer (L7) distributed denial of service (DDoS) attacks attempt to disrupt traffic on a web application by overwhelming it with a flood of traffic.
Structured Query Language (SQL) injection allow bad actors to do things like read sensitive data from a database, modify data, execute admin controls, and sometimes issue commands to the operating system (OS).
Bot attacks use automated web requests to manipulate or disrupt an application or API. Common bot attacks include web content scraping, account takeover (ATO), form submission abuse, and API abuse.
As organizations move their enterprise applications from on-premises hosting to cloud hosting, cloud application security threats present a unique set of challenges. Outside of mitigating the OWASP security risks and application attacks mentioned earlier, many organizations struggle with the complexities surrounding the deployment of applications in the cloud. In fact, some of the most common cloud migration security challenges are due to the fragmentation of security tools and human error. A lack of cloud knowledge from enterprise IT teams, for example, could lead to misconfiguration or accidental errors that facilitate data exposure or loss—especially if this is their first time migrating apps from on-premises to the cloud.
Adhering to application security best practices is challenging, especially for organizations that deploy several enterprise applications both on-premises and in the cloud. Organizations with a distributed workforce typically feature a considerable number of apps in their enterprise IT systems, and the larger an organization is, the more apps it normally requires. This makes application security even more difficult to manage.
According to the 2020 KPMG Cloud Threat Report, 78% of organizations use more than 50 cybersecurity tools to secure their hybrid, multi-cloud environments. Unfortunately, using so many fragmented tools and disjointed security strategies ultimately leads to an inconsistent security posture, a lack of holistic visibility, and higher chances of human errors—all of which open the door to network and application vulnerabilities. Additionally, each cybersecurity tool an organization uses comes with its own management and training costs.
A good start to securing your hybrid workforce is by adhering to the following application security best practices:
For enterprise applications hosted in the cloud, security is a shared responsibility between the cloud provider and the organization. While cloud providers are responsible for the infrastructure applications run on, organizations are responsible for their own cloud application data security measures. Organizations can work to improve their cloud application security by:
Implementing multi-factor authentication (MFA): MFA is a security practice that requires users to present two or more credentials to access an enterprise application. Credentials could include a password, a badge or key, or biomarkers.
Managing user access levels: Only allow users to access applications, resources, or data they need to do their jobs—and ensure continuous device posture assessments are being made while they are using them. Once a user no longer needs access to an application, change their permissions accordingly.
Monitoring end user activity: Keep track of the actions your end users take while using your applications, accessing data, or connecting to unsanctioned networks.
Developing a proper employee off-boarding process: When an employee leaves your organization, be sure to revoke all access to applications immediately and change passwords, as necessary.
Providing anti-phishing training: Educate employees on proper email best practices and how to identify and report phishing attempts.
Using cloud-to-cloud backup services: Protect your information by backing up data stored on one cloud hosting service to another.
As we mentioned earlier, many organizations use a variety of application security tools from different vendors, which leads to an inconsistent or fragmented security posture. To successfully maintain security across enterprise applications hosted both on-premises and in the cloud, it’s important to partner with a vendor that takes a unified, multi-layered approach. A comprehensive, layered application security solution should be comprised of tools that provide:
