In this article, Bliskasoft Corp reviews the latest security protocols and technologies to safeguard data privacy and integrity.
Security protocols, such as cryptographic or encryption protocols, safeguard sensitive data, financial information, and file transfers by using cryptography.
The protocol demonstrates the algorithm’s functionality and provides information such as data structure and representation.
Security protocols can utilize secure multi-party computation, Non-repudiation, secret sharing, encryption, and entity authentication methods.
These protocols guarantee secure data delivery between two endpoints.
8 Important Data Security Protocols
These security protocols do two things. They protect your data and align with PCI requirements for application security.
Encryption
Every day, secrets and credentials risk being revealed or distributed on cloud platforms. Developers might integrate them into code repositories or exchange them through email or chat. Also, they need to ensure they share credentials and other data only after encrypting it.
Encryption is essential to meeting the requirements of PCI DSS compliance. Software engineers should create encryption for all data transferred to and from a platform, as well as any Personally Identifiable Information stored by the platform. Make sure to encrypt passwords, API keys, and all other credentials to safeguard valuable data.
Firewalls
Firewalls are highly effective in combating cyber criminals and malicious attackers. Cybersecurity experts state that a modern firewall is likely to effectively block a range of threats, such as viruses, spam, and malware.
Firewalls are common. However, developers frequently disregard them, and security teams may not keep up with them. The result? A firewall becomes outdated and vulnerable. Maintaining firewalls is the main security standard among the 12 PCI app requirements. Developers need to understand how to configure a firewall and ensure its security.
Cryptography/Cryptographic Agility
The Simple Programmer stated that cryptography is very important for software that stores sensitive data, such as PHI or PII, or follows industry standards like HIPAA or PCI-DSS. Due to the high level of sensitivity of this data, developers must know which algorithms to use in specific scenarios and which algorithms are more powerful than others.
Use cryptography to enhance the confidentiality, privacy, or security of communications sent through insecure channels. Understanding cryptography is essential for developers to ensure the security of your dating platform’s data.
2FA or MFA
Multi-factor or two-factor authentication helps developers ensure the integrity and confidentiality of data. These procedures presume that a user can confirm their identity in multiple ways. For example, two-factor authentication requires a person to either click a special link sent in a one-time email or get a code through SMS.
Thanks to 2FA and MFA, communication platforms are sure to lower the chances of insider threats. 2FA is a fundamental identity and access management measure that verifies the identity of those trying to access important information. Enabling 2FA for platforms such as GitHub is essential in protecting code from theft by hackers, whether it’s in use or not.
SSL Protocol
The SSL protocol, also known as the Secure Socket Layer, provides authentication, encryption, and integrity for data exchanged between the server and the client.
In the SSL handshake process for establishing a secure connection, the session keys (public and private keys) are exchanged, and algorithms are sure to agree upon.
SSL certificates signed by the certificate’s authority need to work well with most operating systems, browsers, and servers to prevent SSL warnings.
TLS Protocol
Two years after its release in 2006, TLS 1.1 was replaced by TLS 1.2 in 2008.
However, numerous certificate authorities have adopted TLS 1.3, which became prevalent in 2018. Leading browser vendors and search engines began implementing TLS 1.2 and TLS 1.3 in January 2020.
SFTP
SFTP is an enhanced form of FTP where files are transferred securely instead of unencrypted. This protocol solves this problem and provides a safe environment for transferring files between local and remote servers. It utilizes a completely secure SSH protocol for connecting. It prevents sniffing attacks to steal passwords and ensures the integrity of data using cryptographic hash functions and data encryption.
IPSec
It secures information at the network level with three protocols: IKE (which stands for Internet Key Exchange), Encapsulating Secure Payload (aka ESP), and Authentication Header.
- The Authentication Header ensures authentication of data origin, data integrity, and safeguarding against repetitive messages. The AH protocol verifies each packet, checking where the software falls short and attempting to take over the session.
- ESP provides validation and integrity for the payload but not for the IP header. It also offers data stream encryption. It utilizes MD5 and SHA standard algorithms.
- The issue of key distribution protocol is addressed by the IKE protocol, which is built on Diffie-Hellman. A security association (SA) is created in the IPsec protocol. A Diffie-Hellman exchange of keys and DNS are used to create a common secret session.
IPSec is commonly used in two primary setups. The initial setup includes a Network Layer Protocol utilized for transferring data between gateways in local networks that are compatible with IPv4 and allow for unencrypted network transmission. The second setup involves securing the data flow within the network by ensuring that all jobs and the web server are compatible with the IPSec protocol.
Today, as experts from Bliskasoft Corp share, almost all modern OS (Linux, Solaris, Windows 2011) support IPSec.
