DDoS surge in mobile and data centers

Besides , exceed 70% Our operational data center reported last year DDoS attack , A substantial increase over the previous year .

according to Arbor Networks Of The first 9 Annual global infrastructure security report (WISR), More than a third of the responding data centers have been attacked more than the total amount of Internet connections available , Almost twice as much as the previous year . What's shocking is that , about 10% Of people suffer more than... Per month 100 Attack .

The report also found that ,DNS Infrastructure remains vulnerable . More than a third of people are DNS Customers who have been affected on infrastructure DDoS attack —— A quarter more than the previous year .

“ Even though DNS The amplification attack is very eye-catching , Including the biggest attack ever detected (Spamhaus), However, there are still a large number of open-ended in the investigation base DNS Parser ,”Arbor The consulting engineer of the operator Andrew Cockburn Speaking group , In blogs in .“ We 20% Of respondents do not limit recursive lookup , When you push it out to DNS The whole foundation of the parser , There is a wealth of options for those who are interested in launching such attacks .”

He added , In the well-known Spamhaus attack after ,Arbor In the next few months, I saw a lot of imitation attacks .“ For all that , The number of open parsers is consistent with last year's survey ,” He said .“ In my submission , Yes DNS There are fewer and fewer internal organizations with specific responsibilities for infrastructure , This is partly the culprit . If there is no targeted and overall safety method , These organizations cannot relate their decision to keep the parser open to the associated security risks .”

The report found , More than a quarter of respondents said there was no formal responsibility within their organization DNS Security team , An increase of... Over the previous report 19%.

Besides , Overall speaking ,DDoS The scale of the attack has risen sharply . In all previous investigations , The biggest attack reported is 100Gbps. This year, , Attack reached 309Gbps Peak value , And multiple respondents reported more than 100Gbps The attack of .

“ And 2012 Compared to , Last year we saw more than 20Gbps The number of attacks is 8 times ,”Arbor EMEA Solution architect Darren Anstee say .“ In short , Attackers seem to have refocused on using high-volume attacks to achieve their goals , This explains why layering DDoS Defense is so important .“

meanwhile , Internal network 、 High level persistent threat (APT) And ubiquitous application layer attacks continue to be IT The daily reality of the Department . See on its network APT The proportion of respondents increased from 22% Add to 30% - Respondents will botted The host is listed as their number one problem .
