Cyber security protocols focus on protecting digital assets. However, a company’s physical assets need protection too.
Physical security protects hardware like modems, network adapters, and cables from theft or damage. It also protects information stored on those devices, such as backup tapes and servers.
Strong data security is based on three key principles: confidentiality, integrity, and availability. This article will explore how security protocols protect your assets at each of these layers.
What are Security Protocols?
Security protocols are sets of rules and procedures designed to protect cyber networks, systems, and data from unauthorized access. They include a combination of authentication, authorization, encryption/decryption, and auditing.
Using security protocols is one of the best ways to protect your business assets, both physical and virtual. The first step is to identify your company’s most valuable assets and determine their value in terms of what damage they could cause if they were stolen or lost. This will help you prioritize your cybersecurity efforts.
The next step is to create a set of protocols that are tailored to your company’s specific needs and requirements. For example, if you have a large volume of financial transactions that take place online, you may need to implement a protocol that can help you prevent DNS spoofing or man-in-the-middle attacks. In addition, you might need to use a protocol that can help you keep track of who is trying to access your network and what they are doing with it.
Most businesses use a variety of different security protocols to protect their assets, and each protocol works differently depending on the type of protection it provides. For example, some security protocols work at the network layer to protect information from being accessed by unauthorized users by encrypting it when it moves between devices on the same network. This includes encrypting data sent between your website and your web browser or between servers on the same network.
Other security protocols work at the application layer to ensure that only authorized users can see the data that is being shared, for instance, SFTP (Secure File Transfer Protocol) or PGP (Pretty Good Privacy). These programs allow users to send messages and files securely between computers.
In addition, a number of security protocols are used at the presentation layer to ensure that only authorized users can view the content of websites and documents. This includes putting timers on how long a user has to log into a website before their account is locked and putting password requirements in place that make it difficult for hackers to crack even the most complicated of passwords.
How do Security Protocols Protect Your Assets?
The Internet has become so omnipresent in our daily lives that it’s easy to forget that dozens of security protocols are constantly at work in the background, keeping your data safe from hackers. Cyber security protocols are the strings of operations that guarantee your information stays secure, whether it’s on your desktop or in the cloud.
To protect your assets, you need a holistic set of security solutions that includes technical solutions, education, and smart habits on the part of team members. For instance, firewalls and encryption prevent unauthorized access by creating barriers between your network and the outside world. Additionally, encryption encodes sensitive data so that only authorized personnel can decipher it.
In addition, you need a strong backup and recovery solution to ensure that your assets are recoverable from a cyber-attack or other disaster. This includes full, differential, and incremental backups. You also need to store your data in different locations to mitigate the impact of a disaster.
Lastly, it’s critical to train employees on cybersecurity best practices so that they can identify threats and follow the appropriate protocols when dealing with company data. In addition, you need to regularly test your security measures for any weaknesses that can be exploited by threat actors.
Finally, it’s important to limit the amount of data you share with outsiders and contractors (e.g., repair technicians and consultants) to the level necessary for them to complete their tasks. Sharing too much information can give a skilled intruder an edge when tampering with your defenses. You should require all contractors and outsiders to sign non-disclosure agreements before being given access to your systems, and you should limit security briefings to only the essentials.
What are the Benefits of Security Protocols?
Security protocols are a series of operations that ensure data is protected as it moves across network connections. This means that hackers or other unauthorized systems can’t read or extract the information and that it remains secure throughout its journey.
This protection can be provided through various methods, depending on the network type and the information being transferred. Encryption is a common method. This keeps the information from being accessible to anyone except the intended recipient, and it is what underpins web browsing that displays the lock icon next to websites using TLS (Transport Layer Security).
Protocols can also be designed to authenticate or authorize users as they enter a system. These may use a password or other credentials and can be set to require certain activities before allowing access. They can also include a timer to prevent an attacker from guessing the password too many times and using stolen login credentials in a brute-force attack.
Other types of security protocols protect a network from physical threats. These are often based on the Open Systems Interconnection model and involve the physical wiring of the network and the security devices installed. They can include locks and keypads that limit access to specific rooms or areas and a security infrastructure that monitors activity and reports potential breaches to staff.
As cyber threats become more sophisticated, it’s important that organizations keep their security protocols up to date. This will allow them to keep abreast of new developments in cyber-attacks and new solutions that can help mitigate these threats.
While it’s not feasible to expect every employee to be a security expert, all employees should be made aware of recommended security practices. This can be done by requiring all employees to sign a Security Agreement acknowledging they understand their responsibilities and will abide by the organization’s security rules. Security awareness can be reinforced by regular, targeted training for all staff members and by frequent reminders displayed throughout the workplace and broadcast through FYI memos and e-mail broadcasts.
What are the Drawbacks of Security Protocols?
There are many types of security protocols, but the most common are encryption and authentication. Encryption protects data from being read by unauthorized users, and authentication ensures that the person trying to access the data is who they say they are. The downside of these protocols is that they can slow down data transmission, which is an issue when it comes to real-time applications.
Another important type of security protocol is a firewall, which blocks malicious software from reaching a computer system or network. A good firewall will also have built-in features that can alert you to suspicious activity, like if someone is trying to log into your system remotely.
In the physical layer, there are protocols that protect the cables, modems, and other equipment that connect you to your data network. These can include things like electromagnetic shielding or complex locking mechanisms to keep out bad actors and other unauthorized entities.
Network security protocols are essential to ensure that hackers, viruses, or other malicious systems can’t access your data or information. They protect data confidentiality, integrity, and availability and are integral to any comprehensive cybersecurity strategy.
These protocols can be found at multiple OSI model layers, but the most popular ones are at the application layer. For example, HTTPS (Hypertext Transfer Protocol Secure) encrypts data on websites to prevent DNS spoofing and man-in-the-middle attacks. It’s why you see that lock icon next to all websites requiring you to log in or conduct financial transactions.
There are a variety of other application-level security protocols that do things like provide data confidentiality, secure digital timestamping, and blind signatures to prove that data existed at a certain time and is not being tampered with or modified in any way.
Another application of network security protocols is virtual private networks (VPNs), which offer a variety of features, including remote work capabilities and data encryption. Most VPNs use a combination of Internet Protocol Security (IPsec) and Transport Layer Security to authenticate communications between endpoints over the Internet.
