• Several companies stopped the service for WikiLeaks although it is not proven that WikiLeaks violates the existing law

• Amazon removed all WikiLeaks content from their servers

• EveryDNS switched off the DNS resolution for wikileaks.org

• Several financial institutes locked up donation accounts

What happened to WikiLeaks?

Finally…

• Thousand of internet users unloaded their accumulated anger starting 7th Dec 2010

• Web servers of Swiss Postfinancebank were down for several hours

• Credit card companies likeMastercard and VISA where notaccessible for several hours/dayover several days

• Paypal’s transaction network wereslow but not taken down completely

• 3 Basic Classes of Attack • L7 (HTTP/Web): Slowloris

• Creates massive concurrent sessions • Firewalls quickly overwhelmed• Server resources completely consumed

• L4: TCP Flood/Syn Flood • Targets any TCP aware device

• L3: ICMP Flood• ICMP protocol attack• Consumes router, Firewall and server resources

• BIG-IP/ASM stopped attacks!• Combination of core TMOS functionality, iRules and

ASM (Application Security Manager)

of network traffic is encrypted bypassing security controls

Traditional network devices are failing under load… 3 out of 6 major firewalls failed under stability testing, and 5 out of 6 were vulnerable to a common exploit.

Security is still expendable… 9 out of 10 IT organizations admit to sacrificing security for performance.

Over 90% of IT administrator want…

Security Context

Security device sprawl is a challenging problem… IT biggest security challenge with device sprawl is operational complexity.

30% Blended attacks… are overwhelming conventional security devices at the edge of the data center.

Security Challenges

11

• Who is the user?

• What devices are requesting access?

• When are they allowed to access?

• Where are they coming from?

• How did they navigate to the page/site?

Context leverages information about the end user to improve the interaction

“Context-aware technologies will affect $96 billion of

annual consumer spending worldwide by 2015. By

that time, more than 15 percent of all payment card

transactions will be validated using context

information.

• DoS = Denial of service

• DDoS = Distributed denial of service

• Layer 1• Cut the cable

• Layer 4 - or Layer 7 DDoS• Thousands of attackers bring down one site

• Layer 7 DoS• One attacker is able to bring down one site

• e.g. Slowloris, Slow POST

DNS is Vulnerable to Attacks

• Multiple DNS attacks: DDoS, Cache Poisoning, Man-in-the-middle• Application timeouts (401 errors)• Lost customers, lost productivity• Loss of Revenue and Brand Equity
