Infinigate Security Day September 9th 2011

Marcel KooringBusiness Development Manager

Agenda

• Introduction

• Statistics from our yearly Work/Life survey.

• Challenges on the Internet– Web 2.0/Social Media– Data Leakage

• Benefits of the Web Gateway

• Benefits of the Email Gateway

3

Web 2.0 / Social Media

4

Facebook users?

• Raise your hand if you have a Facebook account!

5

Social Media in Denmark

• According to the European Union Denmark has 2,566,060 Facebook users on a total population of 5,515,575 citizens!

• That is a 46,5% penetration rate.

6

Results from our work/life research

• 80% of managers see the business benefits of the new social Web.• 48% of managers have identified Web 2.0 usage as an issue of

concern at management level.• 19% of markets in 2011 report that their companies are engaged

in blocking, as opposed to 9% in 2010• There is widespread concern about Web 2.0 among managers,

with 57% expressing security concerns, 48% worried about loss of confidential data via employees

7

Web 2.0 benefits

• Wide variety of useful tools and services that people use in domestic and business life

• Communication is the most common benefit expected• Web-enabled devices and Cloud based services drive usage

forward• The growth of social media for marketing is accelerating

• 41%+ Tweets per day• Monthly Signups 52%• 104% increase in Android apps

• 600k developers• 900k apps• 13B api requests per day

8

On the downside…

• Virus proliferation is much higher on Web than on email

• Popular websites offer a greater chance of malicious infection

• We need Web Security Solutions to allow us to benefit from the web in a save way!

9

Today's Challenges

Even (large) trusted websites are being exploitedLarge sites, with lots of traffic are the ideal way to spread malware.

Dynamic content / Web 2.0/ Social MediaWeb content is not controlled by a single webmaster anymore, but comes from many sources, is user generated and changes rapidly!

Preferred attack vector– The web is becoming the attack vector of choice.

Challenges: •Number and types of sites increasing dramatically• Legitimate sites are used to embed spyware and malware • Proxy avoidance used widely to avoid URL categorization • Encrypted end-to-end content can’t be inspected • Mashups aggregate content from multiple sites• Static URL databases are increasingly ineffective• HTTPS is being adopted widely

10

Spam and Malware

• Short lived success for the good guys

11

Malware

12

Data Leakage

13

Data Leakage

The 4 main reasons of data leakage are:

1. Accidentally publishing information through Email or Web. So make sure you check all web and email traffic

2. Malware designed to steel information. Make sure you protect yourself from malware that is mainly distributed by web and email.

3. Hackers who break there way into networks.4. Employees steeling information for personal gain

14

Data Leakage

• It is a multi headed monster• Do not try to solve everything in one go! Pure-play DLP solutions

are often very expensive and very complex......and until today they have failed to proof their value!

• Start with the obvious and start protecting you Web and Email traffic.

• Clearswift has 20 years of experience in this area and is probably one of few companies that actually have very large, high security customers protecting their information with Clearswifts products on a daily basis!
