Phishing refers to any attempt to obtain sensitive information such as usernames, passwords, or banking details, often for malicious reasons, by impersonating a trustworthy entity in an electronic communication. Phishing is an example of a social engineering technique used to mislead users and exploit weaknesses in network security. Various attempts have been made to control the increase in reported phishing cases, include legislation, employee and general user training, public education, and standardized network security protocols.
Phishing is typically carried out by direct digital communication. An attack will often direct users to enter sensitive information at a fake website, the look and feel of which match the legitimate site. Correspondence, claiming to have originated from social media, auction or retail sites, financial institutions, or network and IT administrators, are used to trap users. Phishing emails may even contain links to distributed malware, further damaging a victim’s system.
In addition to standard phishing techniques, specific types of phishing can be used to accomplish various objectives.
When dealing with web security, it's important to be able to recognize the most common aspects of a phishing attack. Users are often the only reason that phishing attacks are successful, so avoiding major pitfalls can help businesses avoid cyber security threats.
Phishing is one of the largest threats to enterprises today. A successful phishing attack can not only cost money, it can open a company up to much greater security and data breaches. That is why training and education are so important, as they can greatly reduce the rate of successful phishing attacks.
The first step in blocking phishing emails is to install an email filter. Barracuda Essentials provides a comprehensive email filter that blocks spam. It then scans all inbound emails for malicious attachments and URLs against Barracuda’s database of known malicious file types and servers. It also uses advanced analysis to spot signs of phishing such as typo-squatting, link protection, and suspicious language used in the email subject or body.
It’s important to train users to spot potential phishing emails and delete them. Users should err on the side of caution and confirm the authenticity of any unexpected email by contacting the apparent sender. Barracuda Phishline uses advanced training and simulation to measure your vulnerability to phishing emails and teach users how to avoid becoming victims of data theft, malware, and ransomware.
Barracuda Advanced Threat Protection adds more layers of protection for those cases when an inbound email filter alone is not sufficient. First, it uses signature matching, heuristic and behavioral analysis, and static code analysis to pre-filter traffic and identify the vast majority of threats. Finally, it feeds remaining suspicious files to a CPU-emulation sandbox to definitively identify zero-day threats and block them from reaching your network. This means that it can block phishing and emails carrying zero-day payloads that other techniques might miss. Barracuda Advanced Threat Protection is available for Barracuda Email Security Gateways, Barracuda Essentials, Barracuda Web Security Gateways, Barracuda CloudGen Firewalls, and Barracuda Web Application Firewalls.
