Beginning Monday, November 21, 2016, ITCS is implementing a new DNS* security service from Cisco called, OpenDNS. This security service is a cloud-based layer of protection against malware and phishing threats on the ECU network.
How Does OpenDNS Protect Against Malware and Phishing Threats?
OpenDNS is a world-wide network of servers that handle over 80 billion internet requests per day. Updated in real time, this security layer prevents your computer from accessing known malicious websites. This protects your computer against the theft (exfiltration) of your information. OpenDNS also helps ITCS pinpoint compromised computers before a threat spreads throughout the university network.
On Monday, November 21, if you inadvertently try to access a harmful website, it will be blocked, and the web browser will redirect to an ITCS webpage. http://www.ecu.edu/cs-itcs/itsecurity/malicious.cfm.
*What is “DNS”?
The Domain Name System, or DNS, manages the addresses of every device connected to the internet. The DNS has two parts:
- IP addresses
- domain names
Each device connected to the internet is assigned a unique numerical IP address. IP addresses allow devices to connect with each other.
At the same time, internet devices also have a unique, user-friendly alphabetic domain name, like, www.google.com. Domain names are easier for you to remember than the numerical IP address.
When you type a domain address into the search bar of your browser, the Domain Name System (DNS) resolves the alphabetic domain name to the numerical IP address, so you can connect to the other site.
How Can I Avoid Malicious Websites?
Education is the best defense. Here are a couple of tips and reminders to help you avoid a phishing scam:
- ITCS will NEVER ask for your PirateID or passphrase or any other personal information. Your bank and the IRS will not ask, either.
- Never click a non-specific link within an email (example: “Click here”). Mouse over or listen to (if using a screen reader) the complete URL of a message’s links to determine if it’s okay to click.
- Do not open unsolicited email attachments.
- Delete suspected spam and phishing emails.
- Check for the latest phishing scam on the ITCS Notifications page: ecu.edu/itcs/status.cfm.
- Report spam at ecu.edu/cs-itcs/email/spam.cfm
- Forward suspected phishing emails to email@example.com
