The internet is a vast network of interconnected computers that spans the entire world. It has revolutionized communication and is a vital component in the day-to-day operations of most major industries. Cybersecurity is the protection against cyber attacks. Cyber attacks can be as simple as someone trying to access your personal computer without permission or can be a coordinated effort of multiple hackers who are attempting to bring down an entire power grid.
“A new era of cyberwar just started”
The war just started is completed by cyberattacks that aim to destabilize the world financially.
What is Cyber Security?
Cybersecurity is the protection of computer networks, programs, and data from cyber-attacks. They can be intentional or unintentional, but they always have a negative impact on someone or something. There are two main aspects of cybersecurity. One is to protect the system from outside attacks, and the other is to protect the system against any security violations that occur on the inside.
What is Cyber Security Software?
Computer software that aids in the improvement of a computer’s information security is referred to as cyber security software. It protects computers from intrusion, illegal use of resources, hacker attacks, and other threats. When cyber security software detects any dangers in a computer system or network, it alerts the user immediately.
What are the advantages of Cybersecurity?
The advantages of cyber security are as follows: It protects the company against ransomware, malware, social engineering, and phishing. This network security software safeguards end-users. It gives excellent data and network protection. Recovery time after a breach is improved. Unauthorized users are prevented by cybersecurity.
How does Cyber Security work?
A cybersecurity strategy uses many levels of security that are distributed across devices, computers, programs, and networks. It protects your password and secures your network’s digital and physical data from intruders.
Why Cyber Security is Important for Business?
Cyber security is essential since it protects people’s personally identifiable information, sensitive data, and other types of information from theft. It can protect you from attackers’ attempts to do harm.
How to Protect Your Business from Cyber Attacks
Cyber attacks are a reality in our digital world. It is important to keep your business safe from cyber threats by protecting it with the right cybersecurity software.
The best way to protect your business from cyberattacks is to have antivirus software installed on all of your devices, and make sure that you are installing the latest updates for the software. You should also use firewalls and other security measures on your Wi-Fi networks, personal computers and servers.
1. Protect Your Database From SQL Injection
One of the most dangerous (and most common) attacks on web applications is SQL Injection: attackers insert malicious SQL into a dynamic SQL statement. This can lead to an attacker accessing sensitive data, or worse, they could remove all of your site’s data! One of the most common methods of hacking is a SQL injection attack. Hackers use tools like SQL Map or SQL Ninja to find a web app’s vulnerabilities and then exploit them: try using 1′ or ‘1’ = ‘1 as an input value in the username, password, etc., and see what happens. Once SQL injection vulnerabilities are found, they’re easy to exploit and may pose a big threat.
Gladly, SQL injection is also easy to prevent. When creating SQL statements, be sure to clearly mark which pieces of code are the command and which parts contain data. OWASP has a detailed guide on how to parameterize queries in Java (using Prepared Statements or Hibernate) and in other languages.
2. Encode Data Before Using It
SQL injection is just one of many different types of injection attacks. You can disable SQL injections by monitoring and blacklisting user input. Stopping other kinds of injection attacks—LDAP injections, XML injections, XPath injections and OS Command injections for example—is much more difficult than preventing SQL injection
Data can’t interact with code if both are clearly defined. Prevent SQL injection by using a parameterized API. As a result, it is essential to protect the data from prying eyes during an external parsing process, for instance with an XML parser, an OS command shell or a browser.
To avoid executing code by accident, you will need to output encode/escape data before handing it to the interpreter.
The devil is in the details. You need to understand the encoding rules for each interpreter and apply it in a specific context. Make sure you do not encode the same data more than once as browsers can struggle to interpret this. You can’t just HtmlEncode data. You also need to escape the part of the document where you place that untrusted data in order to prevent XSS attacks.
3. Validate Input Data Before You Use It or Store It
You can’t blindly trust data from external sources – it needs to be examined carefully. Files, parameters, HTTP headers, cookies – all remote data needs to be audited by you before raising a web service exception.
Data validation is the process of finding and correcting errors in data that may be input into a system. It is also known as data cleaning. Here are some basic rules to follow when doing so:
- One way to safeguard your application is to do client-side checking and server-side checking. For example, let the browser handle verifying a user’s password while the server checks whether or not they are eligible to log in with that password.
- Use only positive, whitelist validation rules as it will make it harder for hackers to get through. When you can, use whitelist-based rules that clearly define what range of size and values are permissible. Consider using Apache Commons Validator libraries to help you determine what data type is being used.
- You can plugin your validation code to external software for a quick audit, or do in-depth testing of your code by fuzzing it if you want. You can also run static analysis taint checking tools which scan through all of the execution paths in the code and tell you when you are referencing different data.
4. Access Control—Deny by Default
Ensure your access control is thoughtfully planned out in advance. Don’t make these changes later in development without worrying about introducing new bugs or mistakes.
A centralized, server-side access control library has the advantage of being able to manage all the access control rules in one place. This will simplify and reduce errors by removing duplicate code from multiple places. New access control rules can be added to a computer program with relative ease using the access control features of an application framework, or a security library like Apache Shiro.
Use server-side data where possible to make access control decisions. Check if the user is authorised before proceeding with any of the functions.
5. Establish Identity Upfront
Creating a bulletproof authentication and session management protocol can be difficult, as there are lots of places where mistakes can happen. This is why “Broken Authentication and Session Management” is on the OWASP Top 10 list of serious application security flaws. If your application framework doesn’t take care of this properly, then look at a library like Apache Shiro to provide functions for authentication and secure session management.
If you can, try to force multi-factor authentication as it is the safest way to protect your account. However, if you don’t have a choice or only allow password logins, make sure they are at least 6 characters in length and contain both digits & upper and lowercase letters. Please keep your email address safe as it might be used maliciously by people trying to scam you.
When storing passwords, unique salt & hash iterations are useless – you should read OWASP’s Password Storage Cheat Sheet guide to find out more and make sure your passwords are secure.
Recovering passwords can be another challenging process. Make sure you have clear & well-written instructions that can answer all the questions of your customers. The OWASP’s Forget Password Cheat Sheet can help you avoid common password recovery pitfalls when designing your security. For example, the cheat sheet encourages you to use good security questions and properly verify the answers to these questions in order to make sure that we’re not getting hacked.
6. Protect Data and Privacy
Data protection is not that easy and it’s a necessity. We’ve covered enrollment, but there are a few extras we should cover. Auditing will cover access control and logging, while encryption can be used to encrypt data in transit or at rest.
If you have a website or app, we recommend encrypting data in transit by using SSL. It’s not hard, but it takes more work to make sure it is set up and used properly. This cheat sheet from OWASP provides a basic understanding of how these protocols work, as well as guidelines for when to use them. It also demonstrates one way to bypass a Man-In-The-Middle attack.
The most common mistakes in encrypting data at rest are:
- Unencrypted data is exposed, resulting in a breach.
- You should not be developing your own encryption algorithms.
- Incorrect encryption settings can lead to data being leaked or stolen.
The OWASP international non-profit organization has a great Cheat Sheet on Cryptographic Storage of information. It contains the different algorithms you can use and when. You’ll also find many libraries that take care of implementing all the necessary functions for you.
Be careful where you store sensitive data in the processing of a problem. Avoid storing it unencrypted in temporary files and make sure to not include it in logs. You might also want to think twice about storing it in memory.
7. Logging and Intrusion Detection
Logs are important for more than just troubleshooting and debugging, they ensure the security of your business and make it easier to identify critical errors. It also has other uses, including detecting intruders and hackers and recording evidence after a breach. Your logging strategy will also be impacted by these considerations.
Always log a timestamp (as well as other important details like who, where, and what) to aid with your records. To make correlation and analysis easier, follow a logging approach that’s universal across systems. Common frameworks like Logback or Apache Log4j or Log4j2 are very helpful in this regard.
Logging practices should be reviewed & tested. OWASP guidelines will provide you with more information on how to get logging the right way and vulnerabilities to watch out for.
AppSensor is a project from OWASP. It defines common methods of application intrusion checks as well as points in the application where you should add them so that your app will be able to alert you when it is breached. If a server-side update captures a change that should have been updated on the client-side or if it changes an editable field on an uneditable object, then you may have a coding bug in your editing process. Alternatively, somebody may be making edits outside of client-side validation. Don’t log this case and return an error message, instead, throw an alert.
8. Don’t Roll Your Own Security Code
You should learn about your tools and implement them in your workflow. Find out what security features the application framework you are using has to offer as we discussed earlier and use them as needed. If you can’t find any such security tools, there are others that are worth exploring like Apache Shiro or libraries like Hibernate Validator RetValidator. Spring Security, .NET, Ruby on Rails, AngularJS and Play all come with built-in security features that protect you from common issues. Mobile platforms also usually have extra protection solutions available as well.
Frameworks and libraries provide your app with a lot of cool features. But as with any open source project, it’s important to keep your frameworks up-to-date with the latest bug fixes & security patches. The use of vulnerable elements in software has been a popular topic for a while now, and is finally on the OWASP Top 10. Tools like Dependency-Check by OWASP allow you to quickly find vulnerabilities in your app and fix them before your competitor does.
9. Handle Errors and Exceptions Correctly
Error Handling isn’t the most glamorous job, but it needs to be done right. It can lead to some common & serious security vulnerabilities:
- Giving away private information that can be misused by your attackers. You should refrain from giving any clues about the runtime environment and architecture so that attackers cannot access your system easily. Password encryption is crucial for security. Such phrases as “Invalid user” or “Invalid password” can make it hard to discern a phrase like “invalid logon”.
- Inconsistent or absent error handling can cause problems to go undiscovered, erratic behavior, and crashes. In a University of Toronto research, it was found that minor errors in error notification might result in system failures in large systems.
10. Build Security Testing Into Development
With the development speed increasing in Agile and DevOps, security auditors and penetration testers are finding it increasingly difficult to keep up. Security checks must be incorporated into code reviews, and security testing must be automated and included in Continuous Integration and Continuous Delivery pipelines.
Ensure that you have good automated unit and integration test coverage for security functions and controls (such as authentication, access control, and auditing), as well as critical corporate features such as financial code, private data, trade secrets, and admin procedures. This must include both positive and negative assertions.
Gauntlt, BDD-Security, and Zapper (a Jenkins wrapper over the OWASP Zed Attack Proxy) are all capable of automating system-level security tests and checks in CI/CD. These tools make it simple to run security tests and offer easy pass/fail feedback.
Heuristic analysis can be useful, but it isn’t enough on its own. Findbugs and PMD are two tools that static analysis checking may use to detect common security mistakes and other coding concerns integrated into your IDE and into the CI/CD pipeline.
It’s your code, so it’s up to you to make sure it’s safe and secure.
What are the Top 5 Cyber Security Threats Facing Small Businesses?
Small businesses are at a higher risk of cybercrime than larger corporations. Malware, data breaches, phishing attacks, ransomware and social engineering are the five most common cyber security threats facing small businesses. Malware is a type of malicious software that infects computer systems to steal information, disrupt operations or gain access to private computer systems. Data breaches occur when hackers steal customer data such as credit card numbers, social security numbers and driver’s license numbers from a company’s database. Phishing attacks occur when someone tries to trick you into revealing your personal information such as passwords, credit card numbers, or social security numbers.
