Office 365 Security
Phishing is a type of cyber-attack where malicious actors attempt to deceive individuals into revealing sensitive information, such as passwords, credit card numbers, or personal information. They usually do this by disguising themselves as trustworthy sources, such as banks, social media platforms, or other legitimate organisations, and send fraudulent emails, messages, or websites that prompt recipients to provide their confidential data.
Office 365 employs advanced email filtering mechanisms that automatically detect and filter out phishing emails before they reach users’ inboxes. This filtering system uses machine learning algorithms to analyse various characteristics of emails, such as sender reputation, content, and attachments, to identify suspicious patterns and block phishing attempts.
Office 365 includes mechanisms to prevent email spoofing, where attackers forge the sender’s email address to appear legitimate. Technologies like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) are used to authenticate and verify the origins of emails, reducing the risk of attackers impersonating trusted sources.
URL Inspection and Protection
Outlook scans and analyses URLs included in emails to identify potentially malicious links. It can detect and block links that lead to known phishing sites or other malicious destinations. This helps users avoid clicking on harmful links that might compromise their security.
Phishing attacks often involve sending malicious attachments that contain malware or viruses. Office 365 scans email attachments for known threats and can block or quarantine suspicious files to prevent users from inadvertently opening harmful content.
User Training and Awareness
At Valto we provide resources and training materials to educate users about the dangers of phishing and how to recognise suspicious emails. This includes highlighting common phishing indicators like mismatched URLs, generic greetings, urgent requests for personal information, and more.
Advanced Threat Protection (ATP)
Office 365 offers an Advanced Threat Protection add-on that includes additional security layers. It uses machine learning and behaviour analysis to detect and mitigate sophisticated phishing attacks, zero-day exploits, and other advanced threats.
Real-time Alerts and Reporting
If Office 365 detects a potential phishing email, it can send real-time alerts to users, informing them of the potential threat. It also provides administrators with reporting tools to track and analyse potential phishing attacks across the organisation.
While Office 365 provides robust security measures against phishing attacks, user awareness and vigilance are also essential. Educating users about phishing tactics and encouraging them to report suspicious emails can significantly contribute to an organisation’s defence against such attacks.
Microsoft Defender is a comprehensive security solution that employs various techniques, technologies, and insights to protect against phishing attacks. Its capabilities extend beyond email protection, encompassing a holistic approach to safeguarding organizations’ digital environments from a wide range of cyber threats.
Microsoft Defender for Office 365 (formerly known as Office 365 Advanced Threat Protection) helps prevent phishing attacks by employing advanced email filtering mechanisms. It scans incoming emails for malicious content, attachments, and links. If it detects a suspicious email, it can block it, quarantine it, or append warning messages to alert users about potential threats. Using a combination of technologies, including machine learning and behavioural analysis, it helps to identify phishing emails. It analyses email attributes, sender behaviour, message content, and other factors to accurately identify and block phishing attempts. It also checks links within emails to ensure they don’t lead to known phishing or malicious websites and provides real-time protection against click-time URL-based attacks by analysing links at the time of user interaction, thus preventing access to dangerous websites.
Microsoft Defender scans email attachments for malware, viruses, and other malicious content, it uses various techniques, such as signature-based scanning and behavioural analysis, to identify potentially harmful attachments and prevent users from accessing them.
In the event that a phishing attack is successful and a user falls victim to it, Microsoft Defender assists with incident response by providing insights into the attack vector, affected systems, and recommended remediation steps.
Phishing attack simulations offer several valuable benefits to organisations in enhancing their cybersecurity defences. By conducting realistic and controlled mock phishing campaigns, organisations can assess the susceptibility of their employees to phishing attacks. These simulations provide valuable insights into employees’ awareness levels and their ability to recognise and respond to phishing attempts. This proactive approach allows businesses to identify weak points in their security posture and target training and education efforts more effectively. Furthermore, such simulations foster a culture of heightened vigilance among employees, encouraging them to be more cautious when interacting with emails and links. Ultimately, phishing attack simulations contribute to reducing the risk of successful phishing attacks, enhancing overall cybersecurity awareness, and fortifying your defence mechanisms against evolving cyber threats.

Frequently Asked Questions
What is phishing?
Phishing is a type of cyber attack where malicious individuals impersonate trustworthy entities to deceive users into revealing sensitive information, such as passwords, credit card numbers, or personal details.
How do I recognise a phishing email?
Look for signs like generic greetings, urgent requests for personal information, mismatched URLs, spelling errors, and suspicious attachments. Always verify the sender’s email address and be cautious with unsolicited emails.
What’s the purpose of a phishing attack?
Phishing attacks aim to steal sensitive information, spread malware, or gain unauthorized access to systems. Attackers can use this information for financial gain, identity theft, or further cyber attacks.
How can I protect my business from phishing attacks?
Be cautious when clicking on links or downloading attachments from unknown sources. Keep software up to date, use strong, unique passwords, enable two-factor authentication, and consider using email filtering and security software.
What is two-factor authentication (2FA)?
Two-factor authentication adds an extra layer of security by requiring users to provide two different forms of verification, such as a password and a temporary code sent to their phone, before accessing an account.
Can businesses be affected by phishing attacks?
Yes, businesses are often targeted by phishing attacks. Cybercriminals may try to gain access to sensitive corporate data, financial information, or even disrupt business operations.
What is a spear phishing attack?
Spear phishing is a targeted form of phishing where attackers customize their messages for a specific individual or organization, making them appear more convincing and increasing the likelihood of success.
How can organizations prevent phishing attacks?
Organizations can implement email filtering, conduct employee training, run phishing attack simulations, use security software, and adopt strong authentication methods to bolster their defences.
Is it important to educate employees about phishing?
Absolutely. Employee education is crucial in preventing phishing attacks. Regular training and awareness programs help employees recognise and respond appropriately to phishing attempts.
