Description Protecting systems within an enterprise has proven as important to overall security as securing the enterprise perimeter. Over the past few years, the number of vulnerabilities stemming from weaknesses in applications and operating systems has grown dramatically. In direct correlation with the number of weaknesses discovered, the number of viruses, worms, and security attacks has also exploded across the Internet.
To add to the typical virus issues that businesses have had to confront, there are also malicious programs infiltrating organizations today in the form of spyware and adware.
Prevent day-zero attacks Enforce acceptable-use policies Develop host-IPS project implementation plans Evaluate management hierarchy installation options, including single-server, multiserver, and built-in database usage Learn about CSA agents and manual and scripted installation options Understand policy components and custom policy creation Use and filter information from CSA event logs Troubleshoot CSA deployments with agent and management server logs and built-in troubleshooting tools Protecting systems where the private data and intellectual property resides is no longer considered a function of perimeter defense systems but has instead become the domain of endpoint protection software, such as host Intrusion Prevention Systems IPS.
CSA provides the security controls that corporations need to deal with threats to host and desktop computing resources.
Through methodical explanation of advanced CSA features and concepts, this book helps ease the fears of security administrators seeking to install and configure a host IPS. This book explains in detail such topics as installation of the management servers, installation of the agents for mass deployment, granular agent policy creation, advanced policy creation, real-world troubleshooting techniques, and best practices in implementation methodology.
This guide also provides a practical installation framework taken from the actual installation and support experience of the authors. Back cover copy Protecting systems within an enterprise has proven as important to overall security as securing the enterprise perimeter.

The actual evidence and artifacts of compliance, as well as other investigative data, may not meet the customer's goals. All of this can and should be determined before entering into any agreement. Regulation differences. Given global regulatory requirements, SecaaS providers may be unable to assure compliance in all jurisdictions that an organization operates in. Handling of regulated data. Customers will also need assurance that any regulated data potentially vacuumed up as part of routine security scanning or a security incident is handled in accordance with any compliance requirements; this also needs to comply with aforementioned international jurisdictional differences.
For example, employee monitoring in Europe is more restrictive than it is in the United States, and even basic security monitoring practices could violate workers' rights in that region. Likewise, if a SecaaS provider relocates its operations, due to data center migration or load balancing, it may violate regulations that have geographical restrictions in data residence.
itlauto.com/wp-includes/parental/961-retrouver-mon.php As with any cloud computing service or product, there is always the concern of data from one cloud consumer leaking to another. This risk isn't unique to SecaaS, but the highly sensitive nature of security data and other regulated data potentially exposed in security scanning or incidents does mean that SecaaS providers should be held to the highest standards of multitenant isolation and segregation. Security-related data is also likely to be involved in litigation, law enforcement investigations, and other discovery situations. Customers want to ensure their data will not be exposed when these situations involve another client on the service.
Changing providers. Although simply switching SecaaS providers may on the surface seem easier than swapping out on-premises hardware and software, organizations may be concerned about lock-in due to potentially losing access to data, including historical data needed for compliance or investigative support. Migration to SecaaS. For organizations that have existing security operations and on-premises legacy security control solutions, the migration to SecaaS and the boundary and interface between any in-house IT department and SecaaS providers must be well planned, exercised, and maintained.
There are a large number of products and services that fall under the heading of Security as a Service. While the following is not a canonical list, it describes many of the more common categories seen as of this writing:.
Provides a URL category database with over million URLs and accelerates access to specific categories of websites, improving access experience of high-priority websites. Permalink Dismiss All your code in one place GitHub makes it easy to scale back on context switching. Take stock of your applications and modernize them where appropriate as part of a cloud migration. Well, not quite—patching is eventually necessary, but CSA does give you a window of time. The opinions expressed in this book belong to the author and are not necessarily those of Cisco Systems, Inc. Laura — yes, this was not intended be an exhaustive list.
Multi-Factor Authentication , and services that provide reputation. One of the more well-known categories heavily used in cloud security are Federated Identity Brokers. These services help intermediate IAM between an organization's existing identity providers internal or cloud-hosted directories and the many different cloud services used by the organization.
They can provide web-based Single Sign On SSO , helping ease some of the complexity of connecting to a wide range of external services that use different federation configurations. There are two other categories commonly seen in cloud deployments.
Strong authentication services use apps and infrastructure to simplify the integration of various strong authentication options, including mobile device apps and tokens for MFA. The other category hosts directory servers in the cloud to serve as an organization's identity provider. They are most commonly used to manage an organization's sanctioned and unsanctioned SaaS services.
While there are on-premises CASB options, it is also often offered as a cloud-hosted service. CASBs can also connect to on-premises tools to help an organization detect, assess, and potentially block cloud usage and unapproved services. Many of these tools include risk-rating capabilities to help customers understand and categorize hundreds or thousands of cloud services. The ratings are based on a combination of the provider's assessments, which can be weighted and combined with the organization's priorities. Most providers also offer basic Data Loss Prevention for the covered cloud services, inherently or through partnership and integration with other services.
This can be confusing: although the combination of the "security gateway" and "identity broker" capabilities is possible and does exist, the market is still dominated by independent services for those two capabilities. This provides an added layer of protection on top of other protection, such as anti-malware software to prevent malware from entering the enterprise via activities such as web browsing. In addition, it can also enforce policy rules around types of web access and the time frames when they are allowed.
Application authorization management can provide an extra level of granular and contextual security enforcement for web applications. Email Security should provide control over inbound and outbound email, protecting the organization from risks like phishing and malicious attachments, as well as enforcing corporate polices like acceptable use and spam prevention, and providing business continuity options.
In addition, the solution may support policy-based encryption of emails as well as integrating with various email server solutions. Many email security solutions also offer features like digital signatures that enable identification and non-repudiation. This category includes the full range of services, from those as simple as anti-spam features all the way to fully-integrated email security gateways with advanced malware and phishing protection.
Security assessments are third-party or customer-driven audits of cloud services or assessments of on-premises systems via cloud-provided solutions. A relatively mature toolset exists, and a number of tools have been implemented using the SecaaS delivery model.
Using that model, subscribers get the typical benefits of cloud computing: variant elasticity, negligible setup time, low administration overhead, and pay-per-use with low initial investments. In a cloud-based Web Application Firewall WAF , customers redirect traffic using DNS to a service that analyzes and filters traffic before passing it through to the destination web application.
Security Information and Event Management SIEM systems aggregate via push or pull mechanisms log and event data from virtual and real networks, applications, and systems. This information is then correlated and analyzed to provide real-time reporting on and alerting of information or events that may require intervention or other types of responses.
Cloud SIEMs collect this data in a cloud service, as opposed to a customer-managed, on-premises system. They may be offered by cloud services to support customer-managed encryption and data security. They may be limited to only protecting assets within that specific cloud provider, or they may be accessible across multiple providers and even on-premises, via API for broader encryption management.
The category also includes encryption proxies for SaaS, which intercept SaaS traffic to encrypt discrete data. However, encrypting data outside a SaaS platform may affect the ability of the platform to utilize the data in question. They may use a local gateway to speed up data transfers and local recoveries, with the cloud service serving as the final repository for worst-case scenarios or archival purposes. These services roll up traditional security management capabilities, such as EPP endpoint protection, agent management, network security, mobile device management, and so on into a single cloud service.
This reduces or eliminates the need for local management servers and may be particularly well suited for distributed organizations. By nature, most DDoS protections are cloud-based. They operate by rerouting traffic through the DDoS service in order to absorb attacks before they can affect the customer's own infrastructure.
