RAID 5 The minimum number of disks in a RAID 5 set is three (two for data and one for parity).  The maximum number of drives in a RAID 5 set is in theory unlimited, although your storage array is likely to have built-in limits.  However, RAID 5 only protects against a single drive failure .

Start with the last number it will be easier RAID 0+1  : Mirror of Stripes (Raid 0) RAID 0+1 means arrays implemented as RAID 1, whose elements are RAID 0 arrays. RAID 1+0  : Stripes of Mirrors (Raid 1) A RAID 1+0 array is implemented as RAID 0, whose elements are RAID 1 You can read more on this here : http://blog.open-e.com/what-are-raid-1-raid-10-and-raid-01/

Following article cited from www.csoonline.com website What is the GDPR? GDPR is a regulation that requires businesses to protect the personal data and privacy of EU citizens for transactions that occur within EU member states. The European Parliament adopted the GDPR in April 2016, replacing an outdated data protection directive from 1995. The GDPR also regulates the exportation of personal data outside the EU. And non-compliance could cost companies dearly. Companies that collect data on citizens in European Union (EU) countries will need to comply with strict new rules around protecting customer data by May 25. The General Data Protection Regulation (GDPR) is expected to set a new standard for consumer rights regarding their data, but companies will be challenged as they put systems and processes in place to comply. The GDPR leaves much to interpretation. It says that companies must provide a “reasonable” level of protection for personal data, for example, but...

If you get a  Too many connections  error when you try to connect to the  mysqld  server, this means that all available connections are in use by other clients. The number of connections permitted is controlled by the  max_connections  system variable. The default value is 151 to improve performance when MySQL is used with the Apache Web server. (Previously, the default was 100.) If you need to support more connections, you should set a larger value for this variable. Solution provided by user Rob Williams: <?php $link  =  mysql_connect ( "localhost" ,  "mysql_user" ,  "mysql_password" ); if ( mysql_errno () ==  1203 ) {    // 1203 == ER_TOO_MANY_USER_CONNECTIONS (mysqld_error.h)    header ( "Location: http://your.site.com/alternate_page.php" );   exit; } ?> REFERENCE :  https://dev.mysql.com/doc/refman/5.5/en/too-many-connections....

security audits vs vulnerability assessments vs penetration tests vulnerability assessment A vulnerability assessment is a practice used to identify all potential vulnerabilities that could be exploited in an environment. The assessment can be used to evaluate physical security, personnel (testing through  social engineering   and such), or system and network security. Most commercial organizations just want their systems and networks assessed. This means an individual or team runs a scanning tool (Internet System Scanner, Heat, Nessus, etc.). These tools identify running services that typically have vulnerabilities that can be exploited, operating system and application identified vulnerabilities, missing   patches   and hotfixes. The result, depending upon the product, is a long list of every computer system by IP address and their associated vulnerabilities and steps on how to "fix" the vulnerabilities. However, just because something is identified as ...

The following is an extract from veracode official website. When searching for vulnerabilities in websites and web apps, manual web application penetration testing is essential.  Automated penetration testing tools  simply can’t find every flaw – sometimes, it takes the skill and insight of the manual tester to identify complex authorization issues or business logic flaws. Manual web application penetration testing is most effective and cost-efficient when combined with other scanning technologies. Manual testing on its own can be quite expensive and time-consuming, taking weeks to perform a full penetration test. That’s why, when choosing technologies that can deliver state-of-the-art application security, more leading companies today turn to  web app penetration testing  solutions from Veracode. With a full complement of testing solutions built on a leading application security platform, Veracode helps organizations to better protect the software that drives ...
