The networks of financial services firms experience a wide range of network threats, from BGP route hijacks to DDoS attacks and DNS cache poisoning. Yet many firms do not have in-depth, real-time monitoring and alerting for these threats. ThousandEyes helps security and network operations teams to gain in-depth DNS, network and BGP visibility of security events as they're happening. Reviewing real life examples from the financial services industry, we share how to: Visualize key network services such as BGP and DNS Create alerts based on security threats Troubleshoot and take action during situations such as BGP hijacks, DDoS attacks and DNS cache poisoning.

Routes incoming or outgoing traffic to the

wrong network

Three Network Security Threats

Spoofs DNS mappings to

reroute traffic to a malicious

endpoint

BGP Hijack DNS Poisoning

Saturates network links, hardware or

servers to deny service

DDoS

A Primer on BGP Hijacks

AS 14340 Salesforce

AS 2914 NTT

AS 7018 AT&T

AS 3356 Level3

Border Router

Autonomous System Salesforce advertises

routes among BGP peers to upstream ISPs

Salesforce.com advertises prefix 96.43.144.0/22

AT&T receives route advertisements to

Salesforce via Level3 and NTT

AS 4761 Indosat

A Primer on BGP Hijacks

AS 14340 Salesforce

AS 2914 NTT

AS 7018 AT&T

AS 3356 Level3

AS 4761 Indosat

Indosat also advertises prefix 96.43.144.0/22, ‘hijacking’ Salesforce’s

routes

AT&T now directs Salesforce-destined traffic

to Indosat

DNS Cache Poisoning

Local DNS Cache

Authoritative DNS Server

dns.website.com

Attacker

www.website.com

Attacker DNS Server

dns.attack.com

www.attack.com

Attacker inserts a false record into the

DNS cache

Unsecured DNS server, no DNSSEC, no port

randomization

User

User requests DNS record for

www.website.com

Looks up record on spoofed

name server
