Encryption and decryption are both processes designed to keep data private, with the former serving as the reverse of the former. Both tasks serve to safeguard sensitive information, making them both essential components of cybersecurity measures.
Encryption derives from the Greek Kryptos, meaning “hidden or secret.” It was originally used in early communications to transform messages into unreadable groups of figures to obscure their meaning. Nowadays, complex computer technology transforms a message or file into ciphertext that can only be deciphered by both sender and recipient.
Cryptography utilizes both symmetric and asymmetric ciphers. Symmetric algorithms, such as DES, use one key to encrypt a message and another key to decrypt it; on the other hand, asymmetric ones like Rivest-Shamir-Adleman (RSA) use two separate keys – known as a public key and private key – for encryption and decryption purposes.
Cyberattackers frequently leverage encrypted traffic to avoid detection, and this has become a global trend in recent years. From living-off-the-land and Golden Ticket attacks to lateral movement techniques, ransomware, and Log4J exploits, attackers have gained an edge over businesses by remaining invisible.
This allows attackers to conceal initial intrusions, lateral movements and post-compromise activities from most security tools. Furthermore, it enables them to distribute ransomware and other malicious files without detection as well as exfiltrate organisational data.
Network traffic analysis relies heavily on encrypted data for detection and response to advanced attack techniques. Decrypting encrypted traffic allows us to detect SQL injections, cross-site scripting issues, and Log4J exploits in real-time with great detail.
Many organisations are hesitant to decrypt their network traffic due to compliance, privacy and security reasons. Others worry about performance impacts and high computing costs that decryption may incur.
Decryption is an integral component of network traffic analysis, as it allows security and forensic teams to quickly detect and investigate suspicious traffic. Furthermore, decryption serves as a valuable backup measure when continuous packet capture cannot be employed.

What Are the Benefits of Decryption?

Encryption is the process of transforming data into ciphertext that only an authorized individual can decipher. This step is taken in order to keep sensitive information safe from unauthorized individuals or systems.
Encrypting data involves using a key algorithm to transform it into ciphertext, which cannot be deciphered without the key. Once decrypted and decoded by someone with access to the receiver’s key, that ciphertext can be deciphered back to plaintext that can then be read by the intended recipient.
Decrypting encrypted data is a critical function in cybersecurity, and should be taken seriously by all users. It’s mandated by numerous industry and government regulations such as HIPAA, PCI-DSS, and GDPR.
Decryption can be done manually or automatically, and is usually completed through a set of keys or passwords. Decryption serves as an important security measure that guarantees data sent across the internet isn’t viewed or altered during transit.
Encryption and decryption are crucial for several reasons, including privacy and data integrity. Furthermore, encryption and decryption can increase trust between parties.
Decryption has the potential to slow down network performance, especially for devices that must perform both operations simultaneously.
The major drawback of decryption is its lengthy nature. This requires a significant amount of computing power to process and interpret ciphertext.
Some of the most common techniques used to break a cipher are brute force, dictionary attack, and keyword search. These approaches involve running a computer program through all possible combinations of letters and words until it finds one that works.
These techniques may not always be successful, and even when they do work, sophisticated attacks may still be able to defeat them. For instance, DES, an outdated symmetric key encryption algorithm, is vulnerable due to its dependence on using the same key for both encryption and decryption of a message.

What Makes Decryption Vital in Cybersecurity?

Decryption is the process of turning cipher text into plain text so that its intended receiver can read it. It’s an essential function of cryptography as it offers privacy, integrity, and confidentiality to sensitive information.
Decrypting a message requires a key that can break the code. These keys can either be symmetric or asymmetric, depending on which type of encryption is being used. Ideally, the length of this key should match up with the algorithm being used to encrypt it.
Traditional secret-key cryptography relies on the sender and receiver of a message agreeing on an encryption secret key that protects their communications from third parties. This ensures the message cannot be intercepted by third parties.
However, this method can present numerous issues. For instance, the sender must trust that their courier or phone system will keep the secret key secure during transit.
Many companies rely on asymmetric encryption, where both sender and receiver use different keys to encrypt and decrypt their messages. If one key is compromised, the other can still decrypt it securely.
Asymmetric encryption is the most widely used form of cryptography and provides companies with a secure means to keep their information private. Not only does asymmetric encryption encrypt communications, but it also ensures that the sender cannot view the contents of an email before it’s sent onwards.
Another advantage of asymmetric encryption is its resistance to brute force attacks, as computers can perform more complex calculations faster than an individual cryptographer can. This makes deciphering encrypted data much simpler for computer programs.
Ciphers and encryption techniques have been around for centuries, with cryptographers constantly striving to develop new ways to safeguard our secrets. Earlier, ciphers often involved letter shuffling or other methods that made it impossible to decipher what had been written in a message.
Cryphers today are complex and hard to break, especially due to advances in computers like quantum computing. As a result, they’re becoming increasingly important for cybersecurity applications as well as other sectors that rely on confidential data transfer.

Why Is Network Traffic Analysis Crucial for Decryption?

Decryption is the process of converting encrypted data into a readable form. It can be employed to retrieve documents that were previously unreadable due to encryption, or it can be applied to data in order to extract valuable information about them.
Industry analyst firms estimate that 80-90 percent of network traffic is encrypted today. While this can be beneficial as it protects sensitive business and personal information, hackers still have the ability to view and extract important details from encrypted transmissions.
Cybercriminals have become adept at using encryption to hide their communications and go undetected. In many cases, the only way to detect malicious payloads on a network is through decryption tools that analyze encrypted traffic.
Unfortunately, most decryption tools are not as accurate as they could be for detecting threats embedded within encrypted traffic. Furthermore, they require expensive hardware and can be challenging to use in real time.
That is why cybersecurity professionals typically suggest encrypting data before sending it across the network. Doing so ensures that only authorized parties can view your sensitive information, helping prevent security breaches.
However, some data may be more sensitive than others and require decryption. For instance, financial or medical data is typically encrypted before being sent to the bank in order to protect privacy and prevent fraudsters from stealing private information.
In some instances, encrypted data may be necessary to maintain compliance or confidentiality. For instance, a data center might need to encrypt sensitive traffic in order to meet PCI data privacy standards.
Another reason encryption is important is that it shields data from malware and other attacks. Ransomware attackers frequently utilize encrypted information to conceal their activities from network administrators, making it harder for them to be detected.
To protect against this threat, network administrators should implement a comprehensive network traffic analysis solution that can detect and alert suspicious encrypted communication. This will enable them to detect threats early and provide valuable context for rapid detection, scoping, investigation, and remediation of malicious activity.
