One of the main reasons why a user would choose an on-premises ESA versus the CES solution is to have more control over the sensitive data that flows through the email system. With an on-premises ESA, the user can ensure that the data is stored and processed within their own network and data center, and that they comply with any regulatory or organizational requirements for data security and privacy. With a CES solution, the user would have to trust Cisco to handle the data in their cloud infrastructure, and to adhere to the service level agreements and security policies that are agreed upon. Some users may not be comfortable with this level of outsourcing, especially if they have strict data governance or compliance needs12. References: 1: Physical ESA vs Cloud ESA - Cisco Community 2: Cisco Email Security Appliance - Data Sheet

Denial-of-service (DDoS) aims at shutting down a network or service, causing it to be inaccessible to its

intended users.

The Smurf attack is a DDoS attack in which large numbers of Internet Control Message Protocol (ICMP)

packets with the intended victim’s spoofed source IP are broadcast to a computer network using an IP

broadcast address.

Trusted Automated eXchange of Intelligence Information (TAXII) is a collection of services and message exchanges that enable the sharing of cyber threat intelligence across product, service, and organizational boundaries. It is designed to support the exchange of CTI represented in STIX, but is not limited to STIX. TAXII defines an API that aligns with common sharing models, such as hub-and-spoke, peer-to-peer, and subscribe/publish. TAXII is not a public collection of threat intelligence feeds, a threat intelligence sharing organization, or a language used to represent security information. Those are possible descriptions of STIX, which is a complementary standard to TAXII. References: STIX and TAXII Approved as OASIS Standards to Enable Automated Exchange of Cyber Threat Intelligence, STIX V2.1 and TAXII V2.1 OASIS Standards are published, What is STIX/TAXII? | Cloudflare, What is STIX / TAXII?
