Cybersecurity in 2024: The Ultimate Guide to Protecting Your Business and Customer Data

In today‘s hyper-connected digital world, nearly every aspect of life and business involves the internet in some way. We collect, process, store and share unprecedented amounts of data online. An attack on the systems and networks that power our digital infrastructure could be catastrophic – jeopardizing everything from national security to the economy to public health and safety.

This is why cybersecurity has become mission-critical for businesses of all sizes. A single data breach or cyber attack can destroy customer trust, crater your bottom line, and even threaten the very existence of your company.

To help you navigate this complex but crucial topic, we‘ve put together the ultimate cybersecurity guide for 2024. We‘ll cover exactly what cybersecurity entails, review the biggest threats facing organizations today, and share best practices and resources to keep your business and customer data safe. Let‘s dive in.

What is Cybersecurity?

At its core, cybersecurity refers to the practice of protecting internet-connected systems, devices, programs, and networks from malicious digital attacks. These cyberattacks attempt to gain unauthorized access to data in order to steal, expose, alter, disable or destroy information.

Effective cybersecurity involves multiple layers of protection that work together to secure the data, devices, and systems that make up your company‘s digital ecosystem. It requires a combination of technology solutions and security best practices.

The cyberthreats that make strong cybersecurity necessary are wide-ranging – from malware and phishing to ransomware and code injection attacks. We‘ll get into the specifics of the most common types of cyber attacks later on. While even the most robust cybersecurity system can‘t stop 100% of threats, it can significantly reduce your risk and minimize the damage inflicted by successful attacks.

The 5 Main Types of Cybersecurity

Cybersecurity is a broad discipline that encompasses several distinct specialties:

1. Application Security

Also known as AppSec, application security focuses on finding and fixing vulnerabilities in software applications. It involves security considerations at every stage of the software development lifecycle, from initial design and development to deployment and maintenance.

Web application firewalls (WAFs) are a critical component of application security. They monitor, filter and block HTTP traffic to and from web apps, defending against threats like cross-site scripting and SQL injection attacks. At HubSpot, we provide a free WAF as part of our CMS Hub to safeguard your website and content.

2. Cloud Security

As more and more data and business functions shift to the cloud, cloud security has emerged as a top priority. It‘s all about protecting data stored online via cloud service providers like Amazon Web Services, Microsoft Azure, and Google Cloud Platform.

While cloud providers maintain their own robust security, customers share the responsibility. You need to properly configure access permissions, enable encryption, and follow cloud security best practices on your end as well.

3. Critical Infrastructure Security

Certain critical infrastructure, if attacked, could have devastating consequences for public safety and wellbeing. This includes the electric grid, water treatment facilities, communications networks, and transportation systems.

Since much of this vital infrastructure is now internet-connected, strong cybersecurity is needed to prevent hackers from causing massive disruption. The stakes are incredibly high.

4. Internet of Things (IoT) Security

The Internet of Things (IoT) refers to the billions of internet-enabled devices that collect and share data – from smart thermostats to webcams to wearable fitness trackers. Any device that connects to the internet and communicates on its own is part of the IoT.

Since IoT devices access sensitive personal information, lack built-in security features, and are often targeted by hackers, specialized IoT security solutions are essential. This involves securing the devices themselves as well as the networks they‘re connected to.

5. Network Security

As the name implies, network security is about protecting the computer networks that transfer data between devices and servers. It leverages both hardware and software defenses to prevent unauthorized access and misuse of network resources.

Tactics include network access control, network segmentation, firewalls, virtual private networks (VPNs), and security information and event management (SIEM). The goal is to keep hackers out while still providing legitimate users with convenient network access.

15 Key Cybersecurity Terms to Know

To really understand cybersecurity, you need to be familiar with the lingo. Here are 15 key terms to add to your vocabulary:

  1. Authentication: The process of verifying that users are who they claim to be before granting access to systems or data. Usually done through passwords, PINs, or biometric scans.

  2. Authorization: Confirming that authenticated users have permission to access the specific resources they‘re requesting. Not all users are authorized for all things.

  3. Backdoor: A way to access systems or data that bypasses normal authentication methods. Often created by hackers.

  4. Breach: When an attacker successfully infiltrates a network or system and gains unauthorized access to data.

  5. Bot: An software application that runs automated tasks, which can be used for good (chatbots) or ill (sending spam).

  6. Brute Force Attack: Using trial and error to crack passwords or encryption keys. Automated software is used to generate a large number of guesses.

  7. Denial of Service (DoS) Attack: Flooding a network or system with traffic or requests in order to overload and crash it.

  8. Encryption: Converting data into an unreadable format that can only be decoded with the right key. Used to protect data both in storage and in transit.

  9. Firewall: A system that monitors and controls incoming and outgoing network traffic based on security rules. Establishes a barrier between trusted internal networks and untrusted external networks.

  10. Malware: A catch-all term for malicious software designed to cause damage or gain unauthorized access. Includes viruses, worms, Trojans, ransomware, and spyware.

  11. Phishing: A social engineering tactic that tricks people into revealing sensitive info or downloading malware via fraudulent emails or websites.

  12. Ransomware: Malware that encrypts a victim‘s files and holds the decryption key for ransom. Becoming increasingly common.

  13. SSL (Secure Sockets Layer): The standard technology for keeping an internet connection secure by encrypting data sent between a website and a browser. You‘ll see URLs start with "https" instead of "http" when SSL is enabled.

  14. Two-Factor Authentication: An authentication method that requires users to provide two types of identification to access an account – like a password and a code sent to their smartphone. Much more secure than passwords alone.

  15. Zero-Day Exploit: Attacking a software vulnerability that is unknown to the software vendor. The vendor has "zero days" to fix the flaw.

The 8 Most Common Types of Cyber Attacks

While cyber criminals‘ tactics continuously evolve, these eight types of attacks are pervasive:

  1. Malware: Short for "malicious software," malware infects target systems to provide hackers with access or cause damage. Comes in the form of viruses, worms, Trojans, spyware, adware, and ransomware.

  2. Phishing: Masquerades as a legitimate email, text message, or website to trick people into giving up sensitive info or downloading malware. Can be targeted (spear phishing) or broad, automated attacks.

  3. Man-in-the-Middle (MITM) Attack: Attacker intercepts and relays messages between two parties who believe they are communicating directly. Allows hackers to eavesdrop or alter conversations to steal data.

  4. Denial-of-Service (DoS) Attack: Overwhelms a system with traffic or requests, causing it to slow down or crash altogether. Distributed DoS (DDoS) attacks are launched from many different host machines, making them harder to deflect.

  5. SQL Injection: Inserting malicious code into a server using client input, like search boxes or login fields. Lets hackers view, modify, or delete database records.

  6. Zero-Day Exploit: Hackers discover and target a software vulnerability before developers have a chance to release a patch for it. Since no fix is available yet, zero-day attacks can be highly effective.

  7. DNS Tunneling: Encoding data from other programs into DNS queries and responses. Lets hackers bypass firewalls to exfiltrate data or establish communication channels.

  8. Password Guessing (Brute Force) Attack: Bombarding accounts with millions of common password/username combos at high speed using computer scripts. The enormous volume often yields results.

Cybersecurity Best Practices: 7 Tips to Protect Your Business

With the right combination of tools and tactics, you can mount a strong defense against cyber attacks. Follow these seven best practices:

  1. Deploy comprehensive endpoint security: With employees accessing company systems from many devices and locations, endpoint security is critical. Use endpoint protection software to secure every device that connects to your network.

  2. Keep software up-to-date: Promptly installing software updates and security patches is one of the best ways to close vulnerabilities. Consider using automated patch management.

  3. Implement strict access controls: Limit employee access to only the specific systems and data required for their jobs. Use multi-factor authentication and set up role-based access control.

  4. Encrypt sensitive data: Any data you can‘t afford to lose or have exposed should be encrypted, both in storage and in transit. Use secure encryption algorithms and keep your encryption keys safe.

  5. Back up data regularly: In the event that your data is compromised or held for ransom, having clean backups means you can get back to business quickly. Follow the 3-2-1 rule: three copies of your data, on two different storage types, with one copy offsite.

  6. Train employees in security best practices: Your staff can be your best defense or weakest link when it comes to cybersecurity. Train them to spot phishing attempts, use strong passwords, and handle data properly. Build a culture of security awareness.

  7. Work with experienced security professionals: Cybersecurity is complex and ever-changing. Partner with experts who can assess your current cybersecurity posture, recommend improvements, and help you respond to threats.
