Alternative Operations To Strengthen the Login Process
Usernames and passwords alone only provide limited security levels and are relatively easy for hackers to intercept or for users to forget or lose. It is vital to supplement login credentials with technologies that strengthen the authentication process and prevent unauthorized access to networks.
Two-factor authentication (2FA)
Two-factor authentication (2FA) strengthens login credentials by providing an extra level of certainty that the user is who they claim to be. When a user signs in with their username and password, they are prompted to enter a second piece of information that verifies their identity. This information is typically something they know, such as a PIN or passcode; something they own, like a code on an authentication application or on their mobile device; or something they are, usually a biometric factor.
Biometrics
Biometrics are personal attributes or something that the user is, such as their fingerprint, face, or voice. They also include behavioral biometrics, such as a user’s keystroke dynamics or speech pattern. Biometric authentication is commonly used to protect devices like computers and mobile phones to prevent unauthorized access. This adds a layer of security that is more difficult to obtain with traditional login credentials.
Single sign-on (SSO)
Single sign-on is a technique that enables users to log in to multiple services and websites using one set of login credentials. It validates users across various applications using an authentication token to verify their identity to connected service providers. Users only have to remember one set of login credentials, which encourages using a strong, unique password and reduces password repetition.
Threats To User Credentials
Users’ login credentials are highly valuable targets for hackers, who use various techniques to attempt to steal this data. This presents a significant risk to users’ sensitive information, which could be used to commit identity theft or carry out broader attacks against organizations. Several specific attacks target login credentials.
Brute-force attack
Abrute-force attackinvolves hackers using a trial-and-error approach to cracking user login credentials, passwords, and encryption keys. It is a simple, reliable, and popular tactic that hackers use to gain unauthorized access to accounts, networks, and computer systems
Phishing
Phishingattacks involve hackers using login credentialsto send an email from what looks like a trusted sender from a legitimate company. The hacker typically embeds malicious links or attachments in the message or asks the target victim to carry out a financial transaction.
Malware
Malwareis malicious software, such asransomware,spyware, and viruses, that hackers use to take control of a device, gain access to a network, or damage data and systems.
Spyware
Spywareis a form of malware that gathers data from a user’s device and sends it to a third party without their consent, which hackers can use for identity spoofing. Some spyware is designed to damage devices. Hackers can also use spyware to view or steal users’ browsing activity and login credentials.
