Category: Data isolation policies and procedures

Before any plant is inspected, maintained, cleaned or repaired, where practicable, it must be shut down and its energy sources locked out and tagged as part of an isolation procedure often called Lockout Tagout to ensure the safety of those doing the work.

Examples of energy sources include electricity, hydraulic pressure, compressed air or gas, gravity, kinetic spring tension and moving parts. The risks associated with any plant or equipment undergoing inspection, maintenance, cleaning, repair or construction should be assessed and appropriate control measures put in place.

Separate controls away from the plant operator or immediate work area must also be isolated or locked and danger tagged. An isolation procedure is a set of predetermined steps that should be followed when workers are required to perform tasks such as inspection, maintenance, cleaning, repair and construction. Failure to reactivate the plant means that the isolation procedure is effective and that all stored energies have dissipated.

This may require further measures to safely release these energies e. Alternatively, another management approved system that achieves an equivalent level of safety may be used. Out-of-service tags are used to identify equipment or machinery that has been taken out of service due to a fault, damage or malfunction refer to Figure 3.

The out-of-service tag should not be removed until the equipment is safe to be returned to service, or the reason for the out-of-service tag no longer exists.

Go to top of page Isolation procedures. Safety Alert. The aim of an isolation procedure is to: isolate all forms of potentially hazardous energy to ensure that an accidental release of hazardous energy does not occur control all other hazards to those doing the work ensure that entry to a restricted area is tightly controlled.

Risk control measures The risks associated with any plant or equipment undergoing inspection, maintenance, cleaning, repair or construction should be assessed and appropriate control measures put in place. Isolation Procedures An isolation procedure is a set of predetermined steps that should be followed when workers are required to perform tasks such as inspection, maintenance, cleaning, repair and construction.

The following lock-out process is the most effective isolation procedure: shut down the machinery and equipment identify all energy sources and other hazards identify all isolation points isolate all energy sources. When using locks or danger tags, consider the following: tags should be dated and signed locks should be accompanied by a corresponding tag to identify who has locked out the plant tags and locks should only be removed by the person who applied them or by the supervisor after consultation with the signatory of the danger tag.

Out-of-service tags Out-of-service tags are used to identify equipment or machinery that has been taken out of service due to a fault, damage or malfunction refer to Figure 3.

The out-of-service tag may be removed by: the person who attached it the supervisor responsible for the operation or repair of the equipment the maintenance person who carried out the repairs. Related content to Electricity View all.

Back to newsroom.In addition to the protections provided by the firewall and domain isolation, Woodgrove Bank wants to provide additional protection to the devices that are running Microsoft SQL Server for the WGBank program.

They contain personal data, including each customer's financial history. Government and industry rules and regulations specify that access to this information must be restricted to only those users who have a legitimate business need. This includes a requirement to prevent interception of and access to the information when it is in transit over the network.

The information presented by the WGBank front-end servers to the client devices, and the information presented by the WGPartner servers to the remote partner devices, are not considered sensitive for the purposes of the government regulations, because they are processed to remove sensitive elements before transmitting the data to the client devices.

In this guide, the examples show server isolation layered on top of a domain isolation design. If you have an isolated domain, the client devices are already equipped with GPOs that require authentication. You only have to add settings to the isolated server s to require authentication on inbound connections, and to check for membership in the NAG.

The connection attempt succeeds only if NAG membership is confirmed. Server isolation can also be deployed by itself, to only the devices that must participate.

Patient Safety Tool: Sample Isolation Policy

The GPO on the server is no different from the one discussed in the previous paragraph for a server in an existing isolated domain. The difference is that you must also deploy a GPO with supporting connection security rules to the clients that must be able to communicate with the isolated server.

Because those devices must be members of the NAG, that group can also be used in a security group filter on the client GPO. That GPO must contain rules that support the authentication requirements of the isolated server. If you do not have an Active Directory domain, you can manually apply the connection security rules, use a netsh command-line script, or use a Windows PowerShell script to help automate the configuration of the rules on larger numbers of devices.

In addition to the protection provided by the firewall rules and domain isolation described in the previous design examples, the network administrators want to implement server isolation to help protect the sensitive data stored on the devices that run SQL Server. Access to the SQL Server devices must be restricted to only those computer or user accounts that have a business requirement to access the data.

In addition, access is only granted when it is sent from an authorized computer. Authorization is determined by membership in a network access group NAG. Client devices or users whose accounts are not members of the NAG cannot access the isolated servers. All of the design requirements shown in the Firewall Policy Design Example section are still enforced. All of the design requirements shown in the Domain Isolation Policy Design Example section are still enforced.

Woodgrove Bank uses Active Directory groups and GPOs to deploy the server isolation settings and rules to the devices on its network. As in the previously described policy design examples, GPOs to implement the domain isolation environment are linked to the domain container in Active Directory, and then WMI filters and security group filters are attached to GPOs to ensure that the correct GPO is applied to each computer.

The following groups were created by using the Active Directory Users and Computers snap-in, and all devices that run Windows were added to the correct groups. For example, you can make the boundary group a member of the isolated domain group, so that it receives the firewall and basic isolated domain settings through that nested membership, with only the changes supplied by the boundary zone GPO.

However, devices that are running older versions of Windows can only support a single IPsec policy being active at a time. The policies for each GPO must be complete and to a great extent redundant with each otherbecause you cannot layer them as you can in the newer versions of Windows. For simplicity, this guide describes the techniques used to create the independent, non-layered policies. We recommend that you create and periodically run a script that compares the memberships of the groups that must be mutually exclusive and reports any devices that are incorrectly assigned to more than one group.

Instead, these groups determine which users and devices can access the services on the isolated server. This network access group contains the computer accounts that are able to access the devices running SQL Server hosting the WGBank data.

Members of this group include the WGBank front-end servers, and some client devices from which SQL Server administrators are permitted to work on the servers.There are many proper isolation contributions that impact infection control.

Some serve to prevent the transmission of infectious agents in all health care settings.

The elements of a proper isolation need to be performed to prevent disease transmission. See below some listed elements:.

data isolation policies and procedures

Gown, gloves, mask not required for health care workers HCWs or visitors for routine entry into the room. Use of gown, gloves, and mask by HCWs and visitors according to Standard Precautions and as indicated for suspected or proven infections for which transmission-based precautions are recommended. Central or point-of-use high-efficiency particulate air HEPA filters Positive room air pressure in relation to the corridor; pressure differential of 2.

Air flow patterns monitored and recorded daily using visual methods e. Back-up ventilation equipment e. For patients who require both a PE and an airborne infection isolation room AIIRuse an anteroom to ensure proper air balance relationships and provide independent exhaust of contaminated air to the outside, or place a HEPA filter in the exhaust duct.

If an anteroom is not available, place patient in an AIIR and use portable ventilation units, industrial-grade HEPA filters to enhance filtration of spores. There are three isolation categories that reflect the major modes of microorganism transmission in nosocomial setting: contact, droplet and airborne. The rooms of the patients requiring contact precaution should be clearly marked with signs containing instructions regarding the type of precaution.

It is important to make sure that the isolation procedure is being done and hospital policies are enforced. There are no clinical trials to show the value of Isolation Procedures. The key conclusions derive from experience and from a sense of biological plausibility including hand hygiene. Various forms of isolation have been applied in attempt to reduce the spread of healthcare associated infections.

They include contact with blood, other body fluids or secretions and excretions. These precautions also serve to reduce the risk of transmission of infectious agents between patient and healthcare worker, even if presence of an infectious agent is unknown or not apparent. It is strongly recommended to perform hand hygiene before and after every patient contact; to use gloves, gowns and eye protection in situations in which exposure to body secretions or blood occurs; to perform hand hygiene after gloves are removed.

There are many opportunities for avoiding infection. The risk of inadvertent contamination of skin and clothing despite use of personal protective equipment PPE may be particularly high during removal of contaminated equipment.

Taken together these recommendations are reasonable, safe, inexpensive, and consistent with a safety culture for patients and healthcare workers.

Hand hygiene is the single most important measure to reduce the transmission of microorganism from one person to another or one site to another on the same patient. If healthcare workers ignore this most important concept, they will put patients in risk for acquiring infections in the hospital setting and facilitate the dissemination of different organisms such as the multi-drug resistant organisms, Clostridium difficile and all the others that can be related to outbreaks in hospitals.

Gloves must also be changed between patient contacts since many studies show that they become contaminated with MDR organisms. Sometimes, it is necessary to change heavily contaminated gloves while caring for a single patient to prevent cross-contaminated of body sites or if contamination of portable equipment is likely to occur. Such contaminations may contribute to the spread of pathogens known to survive on fomites, such as Acinetobacter species and vancomycin-resistant enterococci VRE.The Oklahoma Foundation for Medical Quality provides a free, downloadable sample isolation policy.

The purpose of the policy is described as the following: "To facilitate patient care for all patients with a known or suspected communicable disease, colonization, or infection, thereby protecting all patients from the acquisition of hospital-acquired infections. It is a lengthy sample policy that addresses a number of aspects of patient isolation including nursing responsibilities, transportation department responsibilities, and guidelines for specific types of isolation including airborne, droplet, and contact.

But with higher traction, hackers come along. Isolation means that a service gives each user the illusion of using the service by themselves. Indeed, one user writing and reading their own data is no very useful. Instead, said data becomes valuable when selectively shared.

Your service may perform isolation in several places, the two extremes being end-point isolation the most common and data-layer isolation. End-point isolation validates a request as soon as received. Then, WordPress uses the same database username and password, both for writing a page as a logged-in user and viewing a page as a guest user.

Hence, once a hacker made it behind the first line of defense, they can talk to the database server directly. Such level of isolation may be sufficient for a website. However, it will certainly fall short when dealing with finances or health data.

For example, the user submits a request with their token. Your service passes that token down the call-chain until it reaches the data layer. Generally, the data-layer consists in a database or an object storage.

Data protection policies and procedures

The data layer then validates the token and matches its claims with a policy. The policy tells what data if at all to serve. Data-layer isolation has the potential to reduce coding errors, since your team need to review less code. Naturally, the policy itself becomes security-sensitive code. Furthermore, said policies might change less often and your team may treat policies with greater care, hence reducing isolation bugs.

Of course, a service may combine the two extremes. As an example, think of a multi-tenant SaaS application serving the users of several companies i. The app may use data-layer isolation between tenants, but end-point isolation between users. One tenant seeing the data of another tenant is a big deal. The latter implements all the fancy sharing features, hence your team will likely change it more often and introduce bugs.

However, if one user sees the data of another user within the same tenant, this is less critical and your team can fix the service quickly. Since end-point isolation is common and well-understood, in the rest of the post we will focus on data-layer isolation. Let us now go through the basic building blocks to achieve data-layer isolation in AWS. Also, I will assume that you have written policies before. Each of these building blocks spans several AWS documentation pages.

Here, we only convey the minimum to understand data-layer isolation and trade-offs involved. In essence, a policy is a list of statements.The Oklahoma Foundation for Medical Quality provides a free, downloadable sample isolation policy. The purpose of the policy is described as the following: "To facilitate patient care for all patients with a known or suspected communicable disease, colonization, or infection, thereby protecting all patients from the acquisition of hospital-acquired infections.

Employee Access.Building and managing a security program is an effort that most organizations grow into overtime. I have worked with startups who had no rules for how assets or networks were used by employees. I also have worked at established organizations where every aspect of IT and cybersecurity was heavily managed.

The goal is to find a middle ground where companies can responsibly manage the risk that comes with the types of technologies that they choose to deploy.

Isolation procedures

In establishing the foundation for a security program, companies will usually first designate an employee to be responsible for cybersecurity. It is standard onboarding policy for new employees. It is recommended that and organizations IT, security, legal and HR departments discuss what is included in this policy.

An example that is available for fair use can be found at SANS. Other items covered in this policy are standards for user access, network access controls, operating system software controls and the complexity of corporate passwords. Additional supplementary items often outlined include methods for monitoring how corporate systems are accessed and used; how unattended workstations should be secured; and how access is removed when an employee leaves the organization.

An excellent example of this policy is available at IAPP. The primary information security policy is issued by the company to ensure that all employees who use information technology assets within the breadth of the organization, or its networks, comply with its stated rules and guidelines. I have seen organizations ask employees to sign this document to acknowledge that they have read it which is generally done with the signing of the AUP policy. This policy is designed for employees to recognize that there are rules that they will be held accountable to with regard to the sensitivity of the corporate information and IT assets.

The State of Illinois provides an excellent example of a cybersecurity policy that is available for download. However, the goal of this policy is to describe the process of handling an incident with respect to limiting the damage to business operations, customers and reducing recovery time and costs.

data isolation policies and procedures

I have also seen this policy include addendums with rules for the use of BYOD assets. This policy is a requirement for organizations that have dispersed networks with the ability to extend into insecure network locations, such as the local coffee house or unmanaged home networks. An example of an remote access policy is available at SANS. I have seen this policy cover email, blogs, social media and chat technologies.

An example of an email policy is available at SANS. The CISO and teams will manage an incident through the incident response policy. If the event has a significant business impact, the Business Continuity Plan will be activated.

An example of a disaster recovery policy is available at SANS.
