When it comes to network security vs data security you need to understand the difference. Network security protects data in transit, while data security protects stored data.

For startups, especially those backed by venture capital, protecting data isn’t just a box to check for compliance: it’s about building trust with investors and customers. These companies often handle a lot of sensitive information, like user data and intellectual property, which makes them attractive targets for cyberattacks. In an environment where the focus is on rapid growth and scaling, having both layers of protection is crucial to keeping the business secure and trustworthy.

And it’s not just a matter of best practices, it’s essential to avoid the costly consequences of a breach: Forbes indicates that data breaches in 2023 increased by 72% compared to 2021, which had previously set the highest record, and according to Statista, the average cost of a data breach globally is about $4.35 million.

The situation isn’t pretty, so it’s important to understand the difference between network security and data security. Our article will go into the roles, tools, and methods you can use to improve the cyber security of your startup.

Key Points

• Network security is about protecting data across the network, data security is about protecting sensitive data wherever it is.

• Both use different tools: network security uses firewalls and intrusion detection systems, and data security uses encryption and data loss prevention to protect information.

• Compliance with regulations like GDPR and HIPAA is a must for organizations to protect data integrity and avoid legal issues, so both network and data security are important.

Network Security vs Data Security

Network security and data security are two sides of the same coin of information security, each with its areas of focus and goals. 

Network security is about protecting data as it traverses the network. It’s about keeping data integrity, confidentiality, and availability during transit. This involves using various security tools and controls like firewalls, intrusion detection systems (IDS), and VPNs to monitor and control access to network resources.

On the other hand data security is about protecting sensitive information from unauthorized access, modification, or destruction, regardless of where it is. It involves using measures like encryption, multi-factor authentication (MFA), and data loss prevention (DLP) to secure data throughout its lifecycle.

Understanding the difference between these two is key to building a comprehensive cybersecurity strategy that mitigates a wide range of security risks. For tech startups, securing both the network and data is critical to protecting sensitive information, building customer trust, and staying resilient as the business grows.

What is Network Security?

Network security is the practice of protecting a computer network from unauthorized access, misuse, or damage. 

Fortinet defines it as “the technologies, policies, people, and procedures that defend any communication infrastructure from cyberattacks, unauthorized access, and data loss.”

It involves using various security controls to protect the network infrastructure, so the data being transmitted within the network is secure. Key methods of network security are segmenting networks to limit attacker exploits and hardening devices to improve security.

Network security is essential. Hackers are getting more clever, so protecting network resources is critical to business continuity and data breaches. Intrusion prevention systems (IPS) and intrusion detection systems (IDS) are key tools to monitor network traffic and detect threats. Additionally, cloud services enhance cybersecurity measures by providing data encryption and continuous monitoring to protect data and applications in the cloud environment.

Network Security Components

Network security involves several key components working together to protect network resources, firewalls, IDS/IPS, and secure VPNs. Each one is important to monitor and control access to network resources, data confidentiality, integrity, and availability.

Firewalls

Firewalls are the foundation of network security, a barrier between internal networks and external threats. They monitor, filter, and control network traffic based on security rules, preventing unauthorized access.

Firewalls come in different types, packet-filtering, stateful inspection, and application-layer firewalls. Each type provides different levels of protection to maintain network resource integrity and confidentiality.

Intrusion Detection Systems (IDS)

Intrusion Detection Systems (IDS) are key to detecting security breaches within a network. They monitor network activity in real-time, looking for abnormal patterns that may indicate a threat. When suspicious activity is detected, IDS alerts the admin for immediate investigation and response.

This layer of defense allows IDS to help organizations detect and contain cyber threats before damage occurs.

Virtual Private Networks (VPNs)

Virtual Private Networks (VPNs) create an encrypted secure connection, commonly known as a “tunnel”, that masks the user’s IP address and improves online privacy. This encryption ensures data transmitted over the network is confidential and secure, so VPNs are essential to protect sensitive information from cyber threats.

With the rise of remote work and online activities, using VPNs is critical to network security and data privacy.

Network Security Threats and Cyber Attacks

Network security faces many threats that can compromise data integrity and availability. Malware like viruses, worms, and trojans aim to disrupt network systems and can cause damage if not contained. In fact, in 2022, the LastPass breach was a reminder that even companies dedicated to security aren’t immune to cyberattacks. Hackers were able to break into the company’s development environment and steal not just source code, but also sensitive customer information, including encrypted password vaults. 

This shattered user confidence and raised big questions about the safety of password management services. It was a clear example of how damaging a network security failure can be, even for businesses whose main job is to protect our data.

Another kind of cyber threat, ransomware, is a type of malware that encrypts files and demands a ransom to access them, is particularly nasty and has become a common threat. In fact, in 2021, the Kaseya ransomware attack hit more than 1,000 businesses around the globe, including many startups. Hackers found a weakness in Kaseya's IT management software, which they used to lock up files and demand a ransom from every affected company. This attack threw many businesses into chaos and served as a stark reminder of the risks tied to using third-party software for essential operations.

Phishing attacks, where emails or messages trick users into revealing sensitive information or downloading malicious files, can result in data breaches and financial losses for startups. Cyber attacks like Distributed Denial of Service (DDoS) attacks flood the network with traffic from multiple sources to disrupt normal operations and cause outages.

IDS are key to defending against these threats by monitoring network traffic and detecting security breaches. Stay alert and implement robust security measures to protect your network from evolving cyber threats.

What is Data Security?

Data security is about protecting private information from unauthorized access and breaches throughout its entire lifecycle. This includes:

• hardware

• software

• storage devices

• user devices

And also implementing access controls and organizational policies.

Good data security practices use tools and technologies like data masking and encryption to improve visibility and data usage.

Compliance regulations like GDPR and HIPAA demand strict handling and protection of personal data. Organizations must follow these standards to reduce risk and protect data.

When it comes to meeting industry standards like SOC 2 and ISO 27001, achieving compliance is a must for building trust and ensuring robust data protection. SOC 2 focuses on maintaining the security, availability, processing integrity, confidentiality, and privacy of customer data, while ISO 27001 provides a framework for managing information security risks.

This is where Oneleet steps in. With our practical approach to security, we help organizations get compliant with SOC 2 and ISO 27001 without falling into the trap of 'security theater'—offering real protection, not just box-ticking. 

Ways to Ensure Data Security

Ensuring data security requires a combination of strategies and tools. Key methods like encryption, multi-factor authentication (MFA), and data loss prevention (DLP) protect sensitive information by maintaining data confidentiality, integrity, and availability.

Encryption

Encryption converts readable data into an unreadable format so only authorized users can access it. Algorithms like AES and RSA encrypt data by converting it into a code, limiting access to those with decryption keys.

This is done to protect data being transmitted over the network and stored on devices, to add an extra layer of security to prevent unauthorized access and data breaches.

Multi-Factor Authentication (MFA)

Multi-factor authentication (MFA) adds an extra layer of security by requiring multiple forms of verification before access is granted. This can be something the user knows (e.g. a password), something they have (e.g. a smartphone), and something they are (e.g. a fingerprint) making it harder for unauthorized access to sensitive data.

Data Loss Prevention (DLP)

Data Loss Prevention (DLP) tools are key to network security to protect sensitive information from unauthorized access and data breaches. Good DLP practices involve monitoring and controlling data transfers to prevent sharing and maintain integrity.

Implementing DLP solutions allows organizations to monitor, detect, and prevent unauthorized data transfers, maintain data integrity, and protect against breaches.

Data Security Risks

Human error is the biggest risk to data security, often resulting in accidental data exposure. Mistakes like sending sensitive information to the wrong person or not following security protocols can be disastrous. Insider threats where employees try to steal data also pose a big risk, hence the importance of non-disclosure agreements and monitoring.

Remote and hybrid working environments increase these risks, creating security blind spots for attackers to exploit. Advanced security measures like hashing protects sensitive data from external threats by changing its face, making it less attractive to unauthorized access.

Network Security vs Data Security

Although related, network security and data security are different aspects of information protection. Network security is about protecting the infrastructure and resources from unauthorized access and threats, data security is about protecting sensitive information from unauthorized access, modification, or destruction.

Focus Areas

Network security is about protecting the network infrastructure, and ensuring data security during transmission. It’s about protecting against unauthorized access and potential risks that could compromise the network’s integrity and availability. Network security aims to achieve this.

Data security is about protecting sensitive information from unauthorized access and ensuring its confidentiality, integrity, and availability throughout its lifecycle. Both are important but address different aspects of information security.

Tools and Techniques

Network security uses firewall security systems and intrusion detection systems to monitor and control network traffic. These tools act as a barrier to protect the network from unauthorized access and threats.

Data security uses tools like encryption and data loss prevention to protect sensitive information. Encryption makes data unreadable, so unauthorized people can’t access it, while DLP monitors, detects, and prevents unauthorized data transfers.

Compliance and Regulations

Various regulatory frameworks and security guidelines, including for example SOC 2, require organizations to implement specific security controls to protect data integrity and confidentiality. Regulations like GDPR and HIPAA have strict requirements on how personal data is collected, stored, processed, and disposed of so startups adhere to high data protection standards.

Compliance is key to trust and avoiding legal action.

Improve Your Company’s Security Posture

Improving your organization’s security posture requires a holistic approach with ongoing processes and practices. Regular assessments to identify current vulnerabilities and potential risks are critical. Proactive monitoring of networks and software for vulnerabilities, regular security control analysis, and establishment of key security metrics are key.

Having a comprehensive incident response plan is vital to deal with security incidents. Assigning specific risks to departments and managers ensures tracking and accountability. Regular backups and encryption are also important for data preservation and recovery in case of loss.
