You&#039;ll have to check out the paper for a more in-depth look.<\/p>\n<p><strong><span>ISO27001<\/span><\/strong><\/p>\n<p>Alexandre Fernandez-Toro, a leading expert on ISO 27001 in France, gives us a presentation focused on two main areas:<\/p>\n<ul>\n<li>Introduction to ISO 27001<\/li>\n<li>Feedback on these ISO 27001 audits<\/li>\n<\/ul>\n<p>If you are not familiar with the standard, I invite you to consult these slides which are well done (or to buy his book).<\/p>\n<p>Regarding the feedback section, Alexandre Fernandez-Toro stirs up quite a hornet&#039;s nest by stating that<br \/>\nISO 27001 does not provide any real security gains if there is no will to secure beyond compliance with the standard.<\/p>\n<p>For him, it is now necessary to read &quot;between the lines&quot; of the ISO 27001 certificate.<\/p>\n<p>Apart from this statement, their experience indicates that the areas primarily impacted by the ISO 27001 process are:<\/p>\n<ul>\n<li>Physical security<\/li>\n<li>PCA<\/li>\n<li>IAM<\/li>\n<li>Taking security into account in the project approach<\/li>\n<\/ul>\n<p>The real security gains from implementing ISO 27001 for &quot;serious&quot; organizations are:<\/p>\n<ul>\n<li>Streamlining security<\/li>\n<li>Pooling of efforts for other standards: PCI, SAS 70 (SOX), RGS (public sector)<\/li>\n<li>Integrating security into corporate governance<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>WOMBAT: The afternoon sessions begin with a presentation of the WOMBAT architecture, used by Symantec [\u2026]<\/p>","protected":false},"author":10,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[65],"class_list":["post-140","post","type-post","status-publish","format-standard","hentry","category-veille-securite","tag-sstic"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.0 (Yoast SEO v27.8) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>SSTIC Live Blogging - Jour 1 Apr\u00e9s-midi - INTRINSEC<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.intrinsec.com\/en\/sstic-live-blogging-jour-1-apres-midi\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"SSTIC Live Blogging - Jour 1 Apr\u00e9s-midi\" \/>\n<meta property=\"og:description\" content=\"WOMBAT: Les conf\u00e9rences de l&rsquo;apr\u00e8s-midi commencent par une pr\u00e9sentation de l&rsquo;architecture WOMBAT, utilis\u00e9e par Symantec [&hellip;]\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.intrinsec.com\/en\/sstic-live-blogging-jour-1-apres-midi\/\" \/>\n<meta property=\"og:site_name\" content=\"INTRINSEC\" \/>\n<meta property=\"article:published_time\" content=\"2009-01-18T16:26:56+00:00\" \/>\n<meta name=\"author\" content=\"Cyrille BARTHELEMY\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:creator\" content=\"@Intrinsec\" \/>\n<meta name=\"twitter:site\" content=\"@Intrinsec\" \/>\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"Cyrille BARTHELEMY\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"4 minutes\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"Article\",\"@id\":\"https:\\\/\\\/www.intrinsec.com\\\/sstic-live-blogging-jour-1-apres-midi\\\/#article\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/www.intrinsec.com\\\/sstic-live-blogging-jour-1-apres-midi\\\/\"},\"author\":{\"name\":\"Cyrille BARTHELEMY\",\"@id\":\"https:\\\/\\\/www.intrinsec.com\\\/#\\\/schema\\\/person\\\/4d0993f0e377e77d13e97f623123e109\"},\"headline\":\"SSTIC Live Blogging &#8211;
