Sony Play Station Network went down one more security beach, according to Sony Official PlayStation blog there is no evidence for stolen credit card detail but Sony even not ruling out the possibility.
“While there is no evidence at this time that credit card data was taken, we cannot rule out the possibility. If you have provided your credit card data through PlayStation Network or Qriocity, out of an abundance of caution we are advising you that your credit card number [excluding security code] and expiration date may have been obtained. For your security, we encourage you to be especially aware of email, telephone, and postal mail scams that ask for personal or sensitive information. Sony will not contact you in any way, including by email, asking for your credit card number, social security number or other personally identifiable information,” said Patric Seybold in the blog post.
I would suggest all PlayStation users to be careful and be vigilant until Sony comes out clean. Make sure to review your account statements and monitor your credit reports daily.
Sony is currently working hard to restore the PlayStation network and hired a recognized security firm to conduct a thorough investigation into what happened.
In 2009 Cisco acquired Pure Digital Technologies was not the brave move, eventually it led to back away from the consumer market by the closure of Flip as part of restructuring. Cisco is expected to reduce its headcount by 550 workers.
May be a better idea for Cisco Systems to concentrate on its core business, especially when there is a rising competition from its rival Juniper Networks and Huawei. I am seeing Huawei gradually making its strong presence in the Middle East market.
According Analysts Flip flopped due to its lack of Internet connectivity, and the proliferation of high end smartphones.
“We have disappointed our investors and we have confused our employees. Bottom line, we have lost some of the credibility that is foundational to Cisco’s success – and we must earn it back. Our market is in transition, and our company is in transition. And the time is right to define this transition for ourselves and our industry. I understand this. It’s time for focus.” said John Chambers CEO of Cisco Systems.
I am looking forward to see how Umi home telepresence going to perform.
A report called ‘In the Dark: Crucial Industries Confront Cyber-attacks’, produced by McAfee and the Center for Strategic and International Studies (CSIS) has revealed that 40% of 200 IT security executives polled believe a major cyber-attack on critical infrastructures may occur over a span of year.
This report surveyed 200 IT security executives from critical electricity infrastructure enterprises in 14 counties, focused on the critical civilian energy infrastructure that depends most heavily on industrial control systems.
Forty percent of the IT security executives from critical electricity infrastructure enterprises believed that the industry’s vulnerability had increased almost 30% and believed that their company was not ready for cyber-attacks.
“We found that the adoption of security measures in important civilian industries badly trailed the increase in threats over the last year,” said Stewart Baker, who led the study for CSIS.
“Ninety to 95% of the people working on the smart grid are not concerned about security and only see it as a last box they have to check,” said Jim Woolsey, former United States director of Central Intelligence.
Some of the key findings of this report
- Eighty percent of respondents have faced a large-scale denial of service attack
- Twenty-five percent of respondents have been victims of extortion attempts
- More than 40 percent of executives believe that their industry’s vulnerability has increased
- Almost 30 percent believe their company is not prepared for a cyber-attack
- More than 40 percent expect a major cyber-attack within the next year
- Energy sector increased its adoption of security technologies by only a single percentage point, at 51 percent
- Oil and gas industries increased by only three percentage points, at 48 percent
- Nearly 70 percent of respondents frequently found malware designed to sabotage their systems
- A quarter of respondents reported daily or weekly DDoS attacks
After reading the complete report it’s evident that there has been an increase in cyber-attacks on critical infrastructure and still most of the organizations are unprepared. Time has come to design the critical infrastructure systems with cyber-security in mind, and organizations need to implement stronger network controls, to avoid being vulnerable to cyber-attacks.
Since its arrival Android is giving a tough time for Apple, plenty of new tablets invented working on Android platform; never the less, Blackberry with its Playbook is expected to do well at least at Enterprise level, HP TouchPad seems to give a tough fight as well. Microsoft is working on Windows 8 eyeing the tablet market and expected to have a demo in June. When all these developments are happening how come Apple can stay idle?
According Reuters the next version of iPhone will go on sale in September 2011, citing three sources with direct knowledge of Apple’s supply chain, the news agency said that production of the iPhone 5 is likely to start in July or August.
The Apple’s next-generation iPhone will have a faster processor but it will be similar in appearance to the iPhone 4, Reuters identified a number of components suppliers for the new phone, namely camera module maker Largan Precision for camera, Wintek to supply the touchscreen, and Foxconn Technology to supply the casing, but none of the vendors would confirm the reports.
Some market observers have suggested that the new phone will be unveiled at an as-yet unscheduled Apple event in September, as Apple has normally held a music-related product launch event in that month. It’s too early to predict the move Apple is going to take; at least I would love to see some restrictions pertained to flash and additional memory expansion are overcome in the new version of iPhone. Not to forget Android is doing an amazing job and its market share is increasing day by day.
Perhaps Apple can come out with a new version of iPad by testing the success of it’s new version of iPhone. Especially when the tablet market is growing exponentially.
In my previous post I was talking about the DNS query problem we were facing with Windows 2008 R2 server. The solution is quite simple. Immediately I started monitoring the logs in the Cisco PIX 525 firewall using ADSM and syslog. I figured out the DNS queries were replied back from the ISP but were dropped by the Cisco PIX 525 Firewall.
%PIX-4-410001: Dropped UDP DNS reply from outside:x.x.x.x/53 to
inside:y.y.y.y/49746; packet length 768 bytes exceeds configured limit of 512
I was wondering what might be the reason, then figured out the packets received from ISP is of 768 bytes whereas by default the Cisco PIX 525 Firewall allows 512 bytes as shown below.
The problem was with the default DNS inspection policy-map. By default in Cisco PIX 525, Cisco ASA it’s configured to 512 bytes
The moment I changed the default DNS inspection policy-map from 512 bytes to 1000 bytes things were normal the Windows 2008 R2 Server was resolving the DNS queries.
The commands I used to change the default DNS inspection policy-map is as follows.
MBGF-DAC-525-FW01# configure t
MBGF-DAC-525-FW01(config)# class-map inspection_default
MBGF-DAC-525-FW01(config-cmap)# match default-inspection-traffic
MBGF-DAC-525-FW01(config-cmap)# policy-map global_policy
MBGF-DAC-525-FW01(config-pmap)# class inspection_default
MBGF-DAC-525-FW01(config-pmap-c)# inspect dns maximum-length 1000
In our new Data Center we added new HP Blade servers and installed Windows 2008 R2 on those servers. Our Servers are connected inside our network behind a Cisco PIX 525 firewall. We are looking to resolve all our DNS queries for the external network using a DNS IP address provided by our ISP which is 212.x.x.2.
In windows 2008 Server we have specified the DNS forwarder as shown in the below diagram.
But it always fails to resolve the DNS queries from internal network to external network using nslookup command from the command prompt of the Windows 2008 Server as well when we are testing the simple and recursive query to other DNS Servers it’s failing as demonstrated below
We have done the following to
1) The internal IP address for the Windows 2008 R2 server is PATed in our PIX 525 Firewall, I could browse the internet.
2) In Windows 2008 R2 Server we have specified the DNS IP Address provided by our ISP.
3) All our servers in the DMZ zone are working fine.
I am working on this issue; meanwhile if any one of you knows who to resolve this issue, your comments are always welcomed.
