How Artificial Intelligence Is Revolutionizing Cybersecurity

Artificial Intelligence (AI) and Cognitive Computing (CC) have opened a new era of cybersecurity.The following are a few examples of how AI can be used to improve and enhance cybersecurity: –

  1. Defending against ransomware – With the introduction of RaaS (Ransomware as a Service), criminals no longer need technical competence to launch an attack. AI-based cybersecurity technologies can regulate attack surfaces and identify/mitigate supported forms of cyber attacks in a large company.
  2. Optimizing cybersecurity in S-SDLC with AI enhancement – If your organization develops software, whether it’s desktop software, mobile apps, online apps, or programs that run on IoT (Internet of Things) devices, you should include cybersecurity in your development process. Occasionally, the development agency lacks the resources to do extensive security testing. This is where AI-powered testing services come in useful. These code testing solutions can perform in-depth code analysis as well as advanced penetration testing.
  3. DGA-Generated domains detection using deep learning algorithms – Domain Generation Algorithms (DGAs) are computer programs that produce pseudo-random domain names (for example – sdlkfusdlfl.com). Malware that calls home (attempts to connect to an external network for command and control) uses pseudo-randomly generated domain names to remain anonymous. DGA algorithms can produce hundreds of thousands of domain names. Trying to ban them all is a pointless exercise because one will get through and connect eventually. In this scenario, AI-based deep learning is being utilized to detect rogue domains generated by a DGA. After viewing enough of these pseudo-random domains, the system is trained to detect them.
  4. Detection, prevention, and remediation of non-malware threats – CryptXXX, CTBLocker, and PowerWare. Web browsers, Microsoft Office applications, and operating system utilities such as PowerShell and Windows Management Instrumentation are frequently used in non-malware attacks. The majority of non-malware threats are recognized by observing computer activity after the incident. Working with a cybersecurity analyst to educate AI-based solutions as well as using neural networks and machine learning algorithms to observe typical behavior, will aid in the creation of improved detection methods.
  5. Stealth, adaptive, and evolutionary Honeypots and Honeytokens – Hackers are attracted to honeypots and honeytokens. Computers, passwords, and other fictitious information are set up on a network to start the process of gathering information about the attack and, eventually, the attacker. The advanced versions of adaptive honeypots and honeytokensare empowered with AI based systems that adapts its behavior in response to the assault, tempting the attacker into revealing as much information as possible. The adaptive honeypot responds by initiating protection in the same way as a protected computer would. When confronted with a new problem, the analyst can learn a lot about the attacker’s skill level and tools by seeing how they respond. As a result, an AI solution can learn and recognize the behavior in the future.

Machine learning and AI can definitely be used to keep updated with the attackers’ tactics in today’s constantly evolving cyber-attacks and proliferation era. Automating threat detection and response are now more effective with use of AI based cybersecurity tools.

What Is Email Masking?

Email masking is a method of changing email addresses to keep sensitive information from being abused. In most cases, a disguised email address retains its original format and cannot be traced back to its source. Email masking is often a part of a larger data masking process that hides sensitive data. The objective is to keep the true information hidden from prying eyes. Email masking can be used for a variety of purposes, such as:

  • To test software or shuffle real user data.
  • Ensure the security of any user data being shared with other parties.
  • Observe privacy regulations and safeguard data in accordance with the standards.
  • Entering masked email addresses on platforms you don’t trust.

In the end, it comes down to whether you want to disguise your personal email address or whether you have a database of user addresses that need to be hidden. Regardless of the reason, this includes the data you keep as well as any copies you make of it. And there are lots of good reasons to make new copies of your users’ information.

The two most frequent techniques of data masking are as follows:

  • Static email masking: Allows you to duplicate a database with data that is identical to the original one. The copied data is then transformed into a new set of data using SQL queries. The objective is to produce realistic records without exposing critical information, as it will be used mostly for testing and development.
  • Dynamic email masking: No copies are generated. Production data is protected with additional layers of security. The major purpose is to ensure role-based database security.

Even though you use the most advanced techniques for concealing genuine email addresses and spend hours modifying your data, something could go wrong at some point. You might miss some records in your database or submit the wrong contacts unintentionally. Some emails may be mishandled by the masking method, and inaccuracies may be difficult to detect in huge data sets. You can mask emails from within your email client if you don’t want to utilize any additional software.

Gmail: Gmail has two features that might be useful:

To begin, add words after the ‘+’ symbol to create aliases of your actual email account. The email address abcdefg@gmail.com, can have the following aliases:

abcdefg+breakingnews@gmail.com

abcdefg+important@gmail.com

You can also send emails from a different address using Gmail.

Outlook: Free aliases and a customizable “From” field are also available in Outlook. To make an alias, go to the Add an alias option and establish a new Outlook.com account. An existing email account can also be used as an alias. Send and receive emails to and from your personal Outlook account. You may send emails from this alias or the account you just added, just like you could with Gmail:

  • Open the Compose window, select “Send From” from the three dots.
  • Then, from the list, choose the required email address.
  • Open ‘Settings’ -> ‘View all Outlook settings’ to alter the default “From” address.
  • Choose ‘Sync email’ from the ‘Mail’ section of the ‘Options’ pane.
  • Finally, in the ‘Set default From address’ section, select the desired email.

You can unmask any email address you want at any time and resume sending from your original account.

Manufacturing Business Security: How To Protect Your Manufacturing Business From Cybersecurity Threats?

Manufacturing businesses across the world were able to operate without strengthening their cyber security posture as that sector initially did not face critical cyber threats. However, the advent of PLC-SCADA (Programmable Logic Controller – Supervisory Control and Data Acquisition), IoT (Internet of Things), Robotic Automation, M2M (Machine-to-Machine) Communication, and State-of-the-Art Technological innovations have attracted the heat from APT (Advanced Persistent Threat) groups. Disrupting production and assembly lines, intellectual property theft, economic and employment failures, and hacktivism are some of the causes and motives that drive attackers apart from just the financial gains.

5 Best practices businesses can follow to protect manufacturing, production and assembly lines from hackers:

  1. Educate and train the employees, partners, and customers: Humans are the weakest link in the entire IT infrastructure that is evident when attackers phish employees for credentials. Security awareness training must be conducted periodically and the company can release advisories and suggest best practices as well. People must be trained to identify, block and report phishing and malicious emails which often is the simplest yet effective way to ward off the biggest cyber threats. Employees must be able to differentiate between genuine and spoofed email senders and user profiles on social media based on a list of red flags provided to them. Everyone in the organizational ecosystem must take ownership of cybersecurity from the entry-level work roles to the C-Suite.
  2. Deploy 2FA / MFA with Biometrics: Implementing 2FA (2-Factor Authentication) and MFA (Multi-Factor Authentication) along with biometric locks will keep unauthorized users or hackers at bay. It is advised to periodically change the credentials used to access the various digital resources across your organization. Modify and update the vendor-supplied default security configuration to customize as per the business requirements. Deploying an appropriate IAM (Identity and Access Management) plan not only prevents an accidental information modification from employees unauthorized to do so but also limits the scope of access for hackers having stolen the employees’ credentials.
  3. Update and upgrade the software and hardware: Always update the hardware and software components used in your equipment and technologies periodically as per the vendor’s suggestions. Your lethargy or temptation to ignore the security updates might attract the attention of attackers to hack into your production systems and cause damage. Customers, partners, and end-users must be notified every time a new hardware or software update or upgrade is available for roll-out with the company. Patch the software for existing vulnerabilities and also design plans for setting up network communication architecture implementing defense-in-depth and depth-in-defense approaches.
  4. Data Privacy & Security with Disaster Resiliency: Companies must be aware of all the T&Cs (Terms and Conditions) about data storage and usage policies of its partners and customers. It is advised to conduct KYC (Know Your Client) background checks before storing any PII (Personally Identifiable Information) or confidential data of your customers and partners. You must encrypt the trade secrets, blueprints, business strategy related files in online and/or offline storage. Utilize encrypted and secure channels to share or transfer data with authorized users and groups. Businesses must aim to procure and deploy a robust and reliable technology tech-stack. The SaaS (Software-as-a-Service), PaaS (Platform-as-a-Service) and IaaS (Infrastructure-as-a-Service) applications must be used along with leveraging Military-grade encryption, Fail-safe Data Backups, Anti-Ransomware Solutions and Disaster Recovery mechanisms to protect your data from loss or corruption in case of any human or natural disaster.
  5. Holistic IT Strategies: Maintaining your organization’s credibility in the market among customers via complying to the various regulatory compliances is very important to protect highly sensitive business information. In-house SOC (Security Operations Center) team can monitor the real-time activities of Users, Services, and Applications in your productions and assembly environment. Alternatively, to facilitate inadequate budgets and lack of resources, you can hire an MSSP (Managed Security Service Provider) to outsource your security logging & monitoring requirements. They help in preventing, detecting, analyzing, & mitigating security risks, threats, vulnerabilities, and incidents. Protect the industrial automation machinery & M2M communication equipments with various security solutions such as NGAVs (Next-Gen Anti-Virus), DLP (Data Loss Prevention), XDR (Extended Detection and Response), Honeypot and likewise. Securing the productions and assembly lines would give Hackers a hard time targeting your manufacturing business.

Web Application Vulnerabilities: Securing Online Applications

Web application vulnerabilities are system flaws that can arise due to improper validation or sanitization of form inputs, misconfigured web servers, or application design flaws. Such vulnerabilities can be exploited by cybercriminals to compromise the application’s security and gain access to use the application as a breeding ground for malware.

Common security vulnerabilities that affect web applications.

  • Injection: This happens when an interpreter receives a compromised query or command. Examples of injection flaws include SQL, LDAP, and OS. The best way to stay protected against injection flaws is to avoid accessing external interpreters. Language specific libraries can be used to perform functions for system calls or shell commands as they don’t use shell interpreter of the Operating System. If a call must be employed (such as calls made to backend database), make sure to validate the data carefully.
  • Cross Site Scripting (XSS): XSS attacks occur when a web application sends data to a client browser without thorough validation. XSS vulnerabilities allow intruders to run malicious scripts on victim browser which spy on user sessions and redirect users to malicious websites in some cases. In order to avoid XSS, applications should be designed to perform vigorous checks against defined specifications. It is recommended to adopt a positive security policy which defines only what should be allowed.
  • Broken Authentication & Session Management: If these functions aren’t properly configured, attackers can compromise user identities and exploit a vulnerability to steal session tokens, keys, and passwords. This type of attack can be avoided by using custom authentication and session management mechanisms. Some session management criteria that should be incorporated include password change requests, password strength checks, session ID protection, browser caching, trust, backend authentication, etc.
  • Cross Site Request Forgery (CSRF): In this case, the attacker forces the victim to send requests that the server will consider to be legitimate. The requests are sent in the form of forged HTTP requests including session cookie of victim and other identification information. To prevent this, applications should use custom tokens in addition to tokens received from browsers because custom tokens are not remembered by browsers to initiate a CSRF attack.
  • Security Misconfiguration: It is important for applications to have a secure application environment. Application developers need to consider guidelines pertaining security mechanisms configuration, turning off unused devices, logs & alerts, etc.
